Zoe, The biggest problem I had for the first few days was going hypoglycemic because I was still taking all my meds. After I cut them out everything was fine. I did get occasional cravings for things like pastries, junk food, but they didn't last long. To a certain extent eating meat (the forbidden, politically incorrect food these days) was so satisfying I didn't miss the other things I didn't eat. Also, not taking my diabetes meds meant if I cheated and ate something I shouldn't, in about an hour I was feeling pretty bad. Built in physical reinforcer. This, plus the ability to eat when you want, really helps. Jim
