I don't know how it will affect me once I've been on atkins for a while, but I already know I'm super sensitive to sugar. I've gone through cycles in the past where I won't touch it for a while, then I'll binge. Sugar makes me incredibly sick and drunk. I react to sugar the same way as most do to alcohol (which is basically sugars anyway). I can get hyper, a bit giddy and feel the rush inside (can't explain exactly), then I'll suddenly feel really, really ill.
