Thanks, John Walker, for the post on aspartame resources. While I can't get details on the web, I read in your post that ONE side effect is "numbness and tingling of feet"--and this is something I started to have some time ago, along with some swelling (as I posted earlier). After being off aspartame for several weeks I noticed the swelling was gone (Peter's also) but I still have the numbness to a degree, and found the possible connection interesting. (Doc said it was due to arthritis.) I should say that we were into long-term use of Equal,etc. so it may be relevant. This was the first I'd seen this particular symptom mentioned...thanks again!
