The most important thing for you is to try and get your problems fixed! This should come ahead of any diet! If they make you drink sugar water, you need to do it, and you should tell them you are doing atkins! I have been having intestinally/nausea problems, and made a point to tell my gasteroenterologist. I think it isn't fair to the doctor if you don't let hime know everything! How is he supposed to fix you if he doesn't know everything? The #1 thing you need to focus on is getting well!
