An updated version of the summary in this post can be found at the following link. As new observations of using Niacin and Xanthinol are posted on the forum, I shall add them to the summary
http://poiscenter.com/forums/index.php?topic=235.msg2958#msg2958This thread is getting quite long! I've read it from start to finish today and decided to bring together all the posts so far in a sort of summary. I'm also seeing Dr Goldmeier tomorrow and wanted a summary to send him. If you think I have misinterpreted your posts please let me know. Also let me know if you've anything to add. For those listed on here,
it might be useful to have a two line summary of your usual POIS symptoms so we can see whether you are a sufferer with mostly cognitive or physical symptoms or both so I can add you in. (sorry I haven't had time to go through and pull out your symptoms from old posts - its taken all dat to read and digest everything already). I hope what I've done is accurate and OK. If I haven't included you and you want to be included in the list please let me know. Perhaps this info would have been better in a spreadsheet but this is what I've had time to do and I'm not sure everything fits neatly into a spreadsheet yet...

Positive niacin/xanthinol nicotinate/nicotinamide experiences
[/b]
VIKTOR.KONS (mostly cognitive symptoms but developed physical symptoms including aches later in life)
Injects 0.5ml Xanthil Nicotinate up to 3 hours before sex. Gets a mild flush No or virtually no POIS symptoms. Tried this for over a year with 4-6 orgasms per week and 2 to 3 per day. He never had to increase the dose to continue the effectiveness.
Tried injecting 1ml Niacin instead of Xanthil Nicotinate. Took more time to have the flush. No POIS symptoms (Orgasm 25mins after injection). However, this is just one day after having Xanthil Nicotinate so possibly there was still some influence from the XN. Second try with (1ml?) niacin injection – bad stomach but could have been alcohol induced. Felt “on the edge of POIS”
tried 600mg Xanthil Nicotinate tablets: very strong flush in 6 mins. NO POIS symptoms but felt “unhealthy”
100mg Niacin tablet: no flush (possibly didn't take enough). 1st day after orgasm: POIS symptoms experienced at 10-20% normal level. 2nd day: no symptoms.
300mg Niacin tablet: felt an increase in strength, heart was working better (this is after long day at work when he was feeling tired and heart (rate?) had gone down. Felt flush in 5 mins and in an hour it was strong. NO POIS SYMPTOMS
150mg Niacin tablet 1 hour before orgasm. Has tried this 3 times and each time had no symptoms.
200mg powdered Niacin. Flush in 5 mins. NO POIS SYMTOMS. (Reports that there were no negative feelings in the stomach which he'd sometimes had with non-powdered tablets).
JIVETALKWas taking niacin regularly (100mg twice per day). Then took 300mg prior to orgasm. POIS symptoms remained at about 60-70% intensity.
Stopped taking the regular 100mg doses of niacin. Then about 45mins before orgasm took 300mg. Felt the flush during orgasm. Initially felt good with only minor symptoms. Next day, no symptoms and then later in afternoon about 60% symptom intensity.
300mg Niacin tablets 60 mins before orgasm. Woke feeling very hot but no symptoms. Subsequently, every few hours POIS symptoms started appearing but, each time, taking a 100mg niacin tablet made them recede (happened 5 times – total 500mg niacin taken throughout this day and about 10% symptoms overall throughout this day). Day3: slight head pressure but not like POIS. 4th day: no POIS at all, “feel great”.
Monday night: 300mg Niacin 40 mins before orgasm. No initial brain fog, slept fine. Tues morning: no brain fog then later 5-10%. Tues night: 300mg Niacin 40 mins before orgasm. No brain fog. Wed morning: no pois symptoms.
Has subsequently been taking 100-200mg Niacin on the day of orgasm. POIS symptoms are consistently reduced to 10-20% of normal intensity.
GUTHRIE300mg Niacin on a mostly empty stomach 40 mins before orgasm. Flush appeared in 5 mins. Flush lasted about 1 hour continuing 20mins after orgasm. Felt better than usual initially. Later in evening, POIS symptoms appeared. Next day POIS symptoms were only 15-20% usual intensity.
Subsequently tried several trials with 100-200mg Niacin. Flushed but not for as long. However, POIS symptoms were not reduced as much as with the initial 300 mg trial.
Tried 300mg again, 2 hours prior to orgasm. Next day, POIS was only 15-20% intensity.
Took two 1100mg Niacinamide (non-flushing) 2.5hours prior to orgasm. No flush. Next day, all symptoms were only 5-10% usual intensity.Reports feeling better than after the 300mg niacin trials.
Thursday night: 1100mg niacinamide. Next day, 10-15% symptoms. Also, unplanned orgasm saturday night. Milder symptoms than normal (is there a residual effect from the niacinamide?) but not as big a reduction in symptoms as just after taking Niacinamide.
POIS_SUFFERER
Been taking 1000mg Niacinamide (not nicotinamide), non-flushing. It's been working well
B_DANIEL450mg of xan-pro tablets (Xanthinol Nicotinate). Mild flush for 20mins. Then had orgasm. Next day, POIS symptoms only 20% usual intensity (and symptoms seemed to fade away later in the day?)
In subsequent weeks: has been taking 1.5 (150mg) XN tablets one hour before orgasm. He can have 3 orgasms within a few hours after taking XN with only minor POIS creeping in one-two days later. Only takes tablets on empty stomach otherwise doesn't have the flush.
Tried Niacin (quantity unspecified) 5 hours before orgasm. It didn't appear to be effective taken that long before orgasm.
KING KONG300mg Niacin 30 mins before orgasm. If he does not sleep about one hour after orgasm he has symptoms of 40-50% normal. If he sleeps for maximum 1 hour after orgasm and then wakes up, his symptoms are only 10% normal intensity.
The day 1 after orgasm he takes regular 100mg doses to help keep POIS symptoms away (up to max 900mg for the day). Day 2 after orgasm he takes 100mg in morning and 100mg in afternoon and symptoms are 10% intensity. Day 3 100mg tablet keeps symptoms at 5% intensity. Day 4: a 100mg tablet and he has no POIS symptoms
HURRAY(mostly cognitive/brain fog symptoms)
Has done two trials of the following: 250mg Niacin prior to orgasm. He gets the flush. After orgasm, symptoms are 30-40% usual intensity.
KK (not sure if this is the same person as King Kong? POIS lasts 5-7days and is worst on days 3 and 4).
300mg one hour after dinner. No flush. The day after orgasm, symptoms were 70-90% intensity.
3 days later: 300mg after dinner. Did get a flush but not until 2.5hours after taking tablets. He had already orgasmed by then, Same results as last time but by day 4 he felt almost back to normal (usually 3rd and 4th days are the worst for him)
500mg Niacin about 12 hours after dinner. Had flush lasting 10mins. Orgasm soon after. Next day symptoms were 30-40% intensity. Days 2 and 3 were even better.
300mg about 12 hours after dinner. Same results as the previous trial.
STARSKYdid his own allergy test with and without taking 300mg Xanthinol Nicotinate. Putting semen on his skin and waiting 30mins usually gives him a reaction. If he has taken XN, he doesn't get a reaction. 6 hours after taking XN, the skin reaction to semen comes back to its 'normal' level.
VINCENT MARKUS100mg Niacin after dinner. Orgasm 1 hour after. Didn't notice a flush but seemed to have more energy than normal in the afternoon of the following day.
200mg Niacin 10 hours after eating. Flush about 30mins after taking tablets. Orgasmed as flush wore off. Felt a bit tired but could think clearly (can't usually). Had a couple more orgasms in the night. Next day felt ok but not 100%. His general stamina and physical energy were increased.
OBSERVERHad a nocturnal emission. Had POIS symptoms. Ate a light breakfast. Took 100 mg Niacin. Intense flush. 50 minutes later – had an orgasm. No POIS symptoms.
200mg Niacin. Weak flush. Orgasm 1 hour later. No POIS symptoms
100mg Niacin. No flush (was after a meal) so took 200mg more. Moderate flush. Orgasm 1 hour later. No POIS symptoms.
200mg weak flush. Orgasm a little after the flush. Some POIS symptoms (mild brain fog)
Next day and with some POIS: 200mg Niacin (on empty stomach). Intense flush. No POIS symptoms (maybe a lttle tired in morning but fine in afternoon.
Has repeated several trials with 200mg since without suffering POIS symptoms
EGORDON200mg Niacin. Flush. Only 10-20% cognitive symptoms after orgasm.
After this initial success, he took supplements including 100mg Niacin/day. Then he took 400mg Niacin on top. No flush. Orgasmed anyway. Usual physical symptoms (burning in eyes and tension in shoulders) mostly didn't appear. Cognitive symptoms about 50% intensity.
300mg Niacin (not sure if he's stopped the regular 100mg doses at this point). Large flush. POIS is less than 10% intensity.
Orgasming twice (each with 300mcg? Niacin before) in 18-20hrs leads to him feeling “terrific” 5 hours later. No POIS symptoms.
Negative niacin results/ other observations:

GABIN (russian forum member):
Tried niacin tablets in doses 200-250mg. Reported that it had no effect on POIS symptoms.
JON200mg in the morning. Didn't feel much effect(ie no flush) and didn't orgasm either. Took a further 400mg at night.Only felt a little tingling (no significant flush). Then orgasmed but there was no POIS prevention.
Took nearly 500mg Niacin. The more he became aroused the more he felt a lot of heat in his head (not sure if this was a flush, it didn't really pass). This was one hour after taking Niacin. Afterwards (presume after orgasm?) felt “crippled", couldn't get up, nerves were sensitive. Wasn't painful to move, just difficult. Groin very sensitive. Doesn't think it helped POIS although a week later perhaps he was more recovered than usual.
Almost 500mg Niacin. Again only a little tingling in the face, no real flush. Orgasmed and sleep was “uncomfortable”. Very irritating to move like he's frozen in bed. Felt a little better than usual the first day after orgasm but POIS symptoms still there.
We are not sure if Jon took flushing or non-flushing or slow-release niacin. HABIBOUAte bread and Nutella. Took Niacin 500mg on half-full stomach. Intense flush after 20mins. Orgasm about 1 hour later. Still got part of the flush after orgasm. Developed POIS symptoms.
CCCONFUCIUSobserved that the flush was “way worse” with 200mg Niacin than with 300mg Xanthinol nicotinate. Also noticed the Niacin “spiked” his heart rate.
