I just started taking a multivitamin and I've been getting a wave of nausea about an hour after taking it. It sorta feels like a "mini flu" (but manageable) I just wanted to know if anyone knows why this is happening? Is it because I'm a lifelong vegetarian and now I'm getting larger amounts of some vitamins than my body is used too? Is there anything I should take to help with the nausea? Am I being a wimp?
