I develop tolorances very quickly and lethargic withdrawal symptoms just as fast when it comes to caffinated diet sodas. I am cutting down... way down. Right now, I'm drinking tomato juice. I actually "got around to" my dieting again. (I was having difficulty unlinking the act of calorie control with the structure of 12-Step programs).
Autists do tend to be highly alergic people. Some people believe that autism may be the result of an alergic reaction to certain foods and/or other environmental stressors. Restricting certian foods is very helpful in maintaining appropriate energy levels and alert states. So far, the best diet I've seen is NeanderThin. It naturally eliminates much of the foods that autists find difficult. It's also great for weight control.
