Thread: I feel sick when I drink Coca-Cola?

It seems like every time I drink Coca-Cola, I feel really sick for about twenty minutes after I finish it, and after that it is just slight nausea. I never have any problems with any other caffeine-containing drinks, although I have quit drinking caffeine for the most part anyways. {Even before I quit caffeine I got the same feeling after drinking Coke.}

Is there anything specifically in Coca-Cola {not diet} that would make me feel sick?

gailysue- Speaking of other Colas, Pepsi usually has the same effect, but less severe. Hah, the only reason I drank it tonight is cause it was in the fridge and my Dr Pepper wasn't.

When you say caffeine-containing drinks does this include the other soft drinks like sprite or root beer?

There are plenty of chemicals and natural ingredients you could be alergic to in Coke....Just don't drink it! I wouldn't do any other Cola's either.
