go without grains and sugars for like 4 months. after that, the craving is gone. your blood sugar has adjusted and basically your body has reset so to speak. you can probably do it in 2-3 months but i abstained from grains, sugars and processed foods for 4 months due to the protocol i was on (yes, it was difficult but drastic times call for drastic measures). my sweet tooth is gone. dont care for chocolate much anymore. when i eat sweets now i get physically ill cos my body is not used to the sugar. i've also noticed that i do TONS better off grains/sugars or limiting them to very small quantities.
there are a lot of baked goods now that are gluten free. all grains have some gluten, to varying amounts, except i believe amarinth, buckwheat, millet, and quinoa (which is actually an herb). you can also make your baked goods (muffins, cakes, bread, cookies, etc) using nut and bean flours. they cook different though. i cant quite get them to rise and set like white flour. still working on this. but they taste great, other than aesthetics.
check out the specific carbohydrate diet (aka breaking the vicious cycle). lots of good ideas there and recipes and meal plans. should help get you started.
