Recommend a good book for me about sugar (addiction).

I want a book that's not a DIET book. Seriously, I don't want it to be focused on losing weight.

I want it to explain what exactly sugar is, how your body handles it, and how to quit being so addicted to it.

I did a low-sugar week (fruits, yogurt, and cereal were all OK, as was limited raw sugar in my coffee, but stuff like doughnuts, ice cream, chocolate, etc. were out). I managed it without too much trouble, and I felt really quite good, both physically and emotionally. After ending that, I've been back "on" sugar for the last few days, and it is fucking with me. With my head, my body, everything. I can't seem to handle it in moderation, maybe with some more structure, I don't know. So I don't know if I can sustain a low sugar...way of eating...over the long haul. I want more proof for myself of why I SHOULD, beyond just what I feel.

Everything at our library looks like it's a diet book. If I have some titles or authors to go off of (or even detailed websites!) I'd feel better about buying something, or doing some ILL for it.
