I'll recommend a different approach.
Read either Anne Catherine's
Anatomy of a Food Addiction or DesMaison's
Potatoes not Prozac.
They won't convince you that carbs aren't your lifeblood...they'll agree with you that they
are, and explain the neurochemistry of this particular addiction in more detail.
Catherine has a several step approach which entails gathering support, dealing with core issues in therapy or 12-step meetings, then abstaining from sugar, then from flour six months later, and finally from fatty foods. (not our bias, clearly, but one could always skip that last step)
DesMaisons emphasizes first getting protein in at all meals, then switching slowly from "white" to "brown" carbs, eating a potato at night to boost serotonin levels (I'd say take a 5-HTP pill instead--but what the heck, if you follow the program, follow the program), and that you will naturally wean yourself from sugar.
Neither of these programs promises miraculous weight loss--moderate weight loss will result--but both emphasize the addictive nature of carbs, deal with addressing that in slower steps (rather than the total cold turkey that so many LC plans suggest).
I hear you saying you'd like to stop the carbs, you're intellectually convinced, but it's too hard. It is hard--what can i say? I still crave sugar in times of stress, and sometimes I even succumb. But the improvement I get through a multiple approach (food, psychology, spirit, community) is steady, and life is long. I encourage you to keep progressing and think about one of these two books as your next approach.
Best of luck to ya!
