You know, it's really interesting how sugar affects me. I've purged myself of all sugar, even fruit and honey, for about 4 months now. I've also cut ALL grains. What I've found is that my body is feeling a lot better and I have more energy in general, though I still haven't built up enough energy to overcome a "chronic fatigue" diagnosis. I still don't have the energy to keep a job, but I have enough energy where I don't want to lay in bed all day anymore. For the most part, my brain is very slowly functioning better all the time too. 4 months ago I could hardly speak coherently because I couldn't think straight, even my dreams made no sense. Now I'm able to think and speak effectively again, but my brain wears out really quickly and I can't processes much through the day before my brain feels tired.
That said, the few times I've allowed an indulgence of 80% organic dark chocolate, I got extremely sugar high and sick and my fibromyalgia pains come roaring back. On the other hand, it caused my brain to turn on in a huge way. While sugar high and feeling super sick to the stomach and in my muscles, I was thinking more clearly than I have in years. I also found myself with a terrible anxiety attack, probably because my brain finally had some cheap easy energy to use to processes all my fears that I've not had the energy to deal with. So I did some research on this. As it turns out, our brains actually require sugar to even operate. However, refined sugar (cane sugar, agave, corn syrup, and the like) actually damage nerve endings in our brains if we eat too much of them. Our brains prefer slow processing sugars, like the ones our body creates from complex carbohydrates. The only carbs I get are from veggies, so I'm thinking of adding even more veggies into my meals to boost my brain power.
Sugar scares the heck out of me, though. I'm quite seriously afraid to ever consume it because of the effect it has on my body.
