Just some interesting information. I, myself am a true aspartame addict. My sister has been warning me for months. I have only recently, made a concerted effort to do away with this stuff. Here is a link to a very good article and a blurp from it.

Dieting Without Aspartame?

"In a cruel and ironic twist, aspartame may actually cause weight gain. Phenylalanine and aspartic acid, found in aspartame, stimulate the release of insulin. Rapid, strong spikes in insulin remove all glucose from the blood-stream and store it as fat. This can result in hypoglycemia and sugar cravings. Additionally, it has been demonstrated to inhibit carbohydrate induced synthesis of the neurotransmitter serotonin, which signals that the body is satiated. Inhibition of serotonin leads to food cravings, increased carbohydrate consumption and, ultimately, weight gain. In a recent study, a control group switching to an aspartame-free diet resulted in an average weight loss of 19 pounds."
