I am a sugar addict too. Not only I have constant sugar cravings, I can have huge amount of sweet items and still crave for more. I can easily gulp down 8-10 chocolate cookies and ask for more.
I too am having hard time controlling myself, but am trying to get up every time I fall and start afresh. The only good thing is that I can tolerate artificial sweeteners, and am trying to use them to subdue my sugar cravings.
I know I have to slowly get over this sugar addiction. Baby steps
