Niacin + exersise during flushing = danger/okay ?

irridia

My doc wanted me to start a niacin regimine. (I think it was 1k mg/day, gotta call this afternoon to verify) I finaly got some last night and as w/all of my meds took it before bed. I knew it was going to cause flushing and some tingling. I was NOT prepared for the insane itching sensation ( I do have atopic dermatitis, excema and have had hives before) , I wanted to claw my skin off. It acutally felt like either hives or a chem burn.

I was wondering if maybe I could work out when it starts to hit, because I think it would help me ignore the sensation and of course busy my hands to keep me from scratching.

Ideas?
