Since I started taking my "new" birth control pills (About a year ago) anything caffeinated has made me very ill. Yes, this includes chocolate except for very small amounts. I have felt SO much better since I cut most sodas out of my diet. I was originally going to switch pills so that this didn't happen, but now I don't mind.

I did enjoy a caffeine free diet coke today, but that's the exception rather than the rule.
