Hi, All --
It seems that several of you either develop high blood glucose (BG) after ejaculation and during the period of POIS -- or suspect that you do.
Daveman has mentioned on the forum that he develops elevated blood sugar while in POIS. He has his own blood sugar monitor that gives him exact readings. Once his POIS passes, his blood sugar normalizes.
If any of you suspect elevated blood sugar levels after ejaculating -- but especially while in POIS-- it might be worth it to buy (or borrow) a BG monitor to check your BG level. (You'll need a few unused lancets!)
Checking the BG once, shortly before beginning the "O" process, then testing your blood sugar a few times/day just until the POIS is over, then once or twice after the POIS ends, might reveal important information about the POIS effect on sugar metabolism. Elevated BG might also might be part of the reason that you all feel so horrendous and brain-fogged during POIS.
When BG is elevated and remains elevated, it means that glucose does not get to it's targets -- the muscles, the heart (which is also a muscle) and the brain. Instead, it stays in the blood stream.
FYI, this doesn't mean that you'll need insulin or other diabetes meds. But it could help shed some light on POIS.
I have no idea if insulin regulation is related to the Vagus nerve, but wouldn't be at all surprised if the two are closely related!
Also, if you have your own BG machine, you won't need to drag yourself out to a doctor's office while in the midst of POIS. They're really not expensive, but sometimes you can borrow one from a friend or even from your doc's office for a few days.
