I agree, you're not on the fast-track to diabetes, but if you were to eat only that for the next 20-25 years, you might be. My own personal opinion? You're addicted to sugar, plain and simple. When your body runs out, it makes you go get more, and thus the cycle continues. Anxiety and stress (the fight or flight response) can also make your body want it. It's a quick source of energy, but then if there's no actual emergency, well, that's where it has to get processed and stored and when all the bad things happen. I was addicted to sugar myself, but about 14 months ago I quit cold turkey. Not only refined sugar, but things like starches (white potatoes are an example) and fruit (fructose). I really went off the deep end. And it sucked, 8-12 weeks of torture, but afterword, oh my goodness. The flavors that food has is amazing. I like stuff I used to detest (squash, for one) and I no longer crave the sugar. I added small amounts of fruit after 4 months, and I never looked back. I also went totally radical and cut out dairy and gluten for good measure.
So, to sum it up, I think you're addicted to sugar. It won't kill you, it just makes you miserable for a variety of reasons. It did me, and now I'm free of it. Good riddance.
