You're not alone: sugar is the only thing I'm really addicted to, other than maybe the Internet.

The only thing that has worked for me is going completely cold turkey for my two big sugar vices: candy and soda. I haven't had candy in about a year, and I haven't touched soda in three or four years. It gets easier...I don't really crave either of those things ever anymore. I still eat things that have sugar, but I don't really go overboard with anything other than candy and soda, so it's not a problem.

Quit cold turkey; some of us can't handle moderation for some things.
