I know some people talk about certain supplements (L-Glutamine, I think) that help control cravings. Atkins talks about them somewhere, probably in his book or on the website, I don't recall.

I think the best way for you to get back into it is just jump in full force. Throw out food you can't eat and just start for a couple days. You know that once the physical cravings are over you'll feel better. Then you just have to deal with psychological ones. This can be hard, but with all these people (and the dream of a healthier, thinner self) you may as well try, right? And next time, if you slip, you'll do your best not to fall all the way in, because you'll remember how you feel right now wishing you hadn't gone back to your old ways.

I wish you luck. I appreciate the difficulty of this and hope you can regain control of those demon carbs!
