Hello Dusak92, the most important question is: when are you taking it?
What it works for most of us is to follow a specific protocol-
- Take a crushed niacin - turn it into powder- (around 200 mg if you weight around 80 kg) and wait for the flush to appear.
- After the flush has started to recede, AND, at least after 50 minutes have passed since you took the niacin, you have a
"window of opportunity" to have as many O.s as you want in the next 3 hours.
- Several POISers (including myself) have said that they experience a relief around 50-100%. In my case I don't have any POIS symptoms, they are completely eliminated, except for a small constipation.
