Sugar is poisonous and it promotes the growth of harmful gut bacteria that influence your brain chemistry to make you crave more sugar. Cut out all sweets and sweeteners except raw honey for a couple weeks and you'll feel like a different person. You'll sleep better, you'll have more energy, and pretty quickly you won't crave sugar. I broke my sugar fast a bit over the last week visiting with some friends and I immediately felt gross. Be careful to not replace those sweets with extra carbs.
