Amelie, here are two thoughts I have...hope they will help.
1. For me, one of the great motivators on SBD is no longer craving. When I'm not craving, I might look at something like fudge and wish I could eat it, but I don't have the intense, crazy longing and obsessive thoughts about it that I usually have. It takes getting off the sugar to get off the cravings (Phase 1) and it hurts to eat the sugar (headaches, dizziness, being really crabby)...so it's a great motivator not to start. What *I* need is motivation not to overeat on the things I can have after overindulging in SF food.
But when I'm not craving, I don't do that either...it's mostly an emotional thing. Perhaps it's emotional for you? If so, journaling can help, joining OA can help (
www.oa.org), and there are other things...so think abou that, too.
2. Sandi, our spotlight dieter, has this in her sig: "If you want to do it, you will find a way, if you don't, you'll find an excuse." 'Nuff said. We both know you can do this if you really want to.
