I've used aspertame containing drinks, foods, candies etc. for 3 years now, and have found no bad effects. I've lost weight very rapidly while drinking 2-3 diet sodas/drinks a day and eating sugar free candies. The only thing I've noticed is the candy, if you over do it... you'll get horrible gas! My personal favorite diet drink is sugar free Kool - Aid! Tropical punch flavor is soooo yummy!!! Good luck with whatever you choose to do!
