i'm wondering about my red face. someone told me there are 2 types of niacin and if one over-eats the one, there is increased flushing. what do you think? i suspect it is the sinemet. i believe i'm taking too much sinemet; feel miserable as i did when took eldepryl, mirapex, comtan. i'm checking into shy-drager because my BIG problem is weakness, rubbery legs and i think that could be low bp/pulse. nancy spires
