This is an addendum to the thread the other day about aspartame. Last Friday I had my first diet soda in about 2 years, and had a few more over the weekend. Lo and behold, that old stomach pain of mine came back, with a vengence. Whether it's the aspartame or the acid in the soda, I'm not sure, but I suspect the aspartame, which also gives me bladder spasms. I can drink bubble water without problems. Well, it was a wake up call, and I won't touch the stuff again. I'll stick to iced tea with Stevia, or an occasional RC cola if I have to. Just my 2.5 cents! Beth.
