I have the same problem in the evenings...after reading the Carbohydrate Addicts book, I'm getting convinced I may have a problem with insulin that still hasn't been controlled. The way they describe how repeated snacks can cause a "building" effect with the insulin, until the urge to eat becomes nearly unbearable, certainly decribed me before Atkins, and to an extent, STILL...

I'm considering giving up my artificial sweeteners and snacking for awhile, just to see if the evening cravings go away.
