I tried some niacin yesterday (I forgot about the flush). I felt totally sick from it and I had the worst stomach cramps, just these waves of very acute pain that doubled me over until it passed. My skin was red as a tomato all over, from head to toe. Not sure why I got so sick or if I should try to find one that doesn't flush the person.

I asked over at the new Vitamin forum here if anyone has any info on B3 that they could share about doses, side fx, etc. Hopefully one of the local gurus there might be able to help us to understand more fully effects of taking B3.

I thought the B vitamins weren't very risky. Then again I never expected to be sick yesterday either. I swear it felt like I was having contractions.
