Here's an interesting development on the subject of fasting:
http://www.newscientist.com/article/dn27001-no-need-to-starve-to-get-fastings-immune-benefits.html#.VW7R5qYmUqY
I've currently been fasting for about 62 hours (water, and occasional tea or bouillon vegetable broth only). I plan to end this fast in about an hour so that I am prepared for a relatively active weekend. I know there is one research paper saying fasting for 72 hours can "reset" the immune system. I am tempted and feel ok but I think I need a bit longer to recover before my weekend. In any case the 72 hour thing was preliminary research and it sounds like it can be between 2 and 4 days. I'm not doing 4 days, certainly not without medical supervision anyway. I'm not sure when/if I'll test this fast with an ejaculation but will report back if I find anything has changed in terms of POIS.
Interesting article, Mellivora.
It says that fasting OR exercise leads to the production of the anti-inflammatory ketone this researcher is working on ( called BHB).
It is known that exercise has an anti-inflammatory effect. I have noted that exercise is good for my POIS symptoms. Throughout the years, I have noticed that I can not exercise when symptoms are too severe, because I have too much hypotension and fatigue, and exercising is making me feeling more ill, if possible. But I have noticed that exercising when symptoms were down at 30 to 50% would almost get me rid of all those remaining symptoms. If remaining symptoms where at 30% or less ( that was on day 2 or 3 , before I had my current method of control and prevention), 1 hour of exercise would clear me for sure of any remaining symptoms.
Now, I can exercise the day of an O if I took my pre-O pack of supplements, and get rid of symptoms that would have resist pre-O and post-O prevention and self supplementation. I do not feel top shape if the POIS acute phase was in the more severe side, but will be ok anyway to go about my day and interact normally with others. And, everything will be normal and will feel no symptoms at all if the POIS attack was milder ( the intensity of my symptoms are not always the same - sometime lower, something more severe, and I don't know the reason yet of this difference in intensity). For sure, I am not cured, but gone are the days when I would be defenseless about becoming a grinch for 3 days and live with a total lack of energy, overpowered by anxiety and lack of motivation, just waiting for the POIS nightmare to be over.
If fasting or exercise are good for POIS symptoms, and that it is linked to their positive effect on inflammation, that would confirm that POIS has at least an immune aspect in its cause, and as I have shared lately, I think it is so.
