stop taking vitamin C and see if you feel better. It could be that it's not the vitamin C, but something else in the pill (fillers) that's causing the problem. You could always try another brand of vitamin C.

I can tell you that there are certain vitamins that you can overdose on, but I think the biggest danger is with the vitamins than are not water soluble which, I think, are A, D, and E.
