wishing you well in your efforts, Mouser. Want to tell us why you made this decision?
I read that anyone suffering from symptoms we usually associate with caffeine should also look at their intake of the far more dangerous drug, aspartame, which is found in virtually all diet soft drinks and many other products. It's only becoming known recently how very addicting -- and neurologically dangerous -- aspartame is. Also very insidious, because it's not always mentioned on the label.
Check out these toxicity symptoms (and if you want to read more, stay away from the information provided by junk food industry PR organizations):
dizziness
shaking hands and other tremors

rapid heart beat, tachycardia (another frequent reaction)
slurring of speech
memory loss
confusion
numbness or tingling of extremities
