hi bud, can't say i'v had any major probs on the diet myself, have been on a very low calorie/fat/carb diet for nearly 2 and a half months, guessing it's your body rebelling at such a different diet to what you would normally consume, remember this is in essence a de-tox diet, and you ain't taking in no crap, so your body don't like it, it'll pass, if not you'll have had surgery by then anyways, how ya feeling, not long for you either bud??
