I believe if you give atkins a try and be very pure about it for the first 2 weeks you will not need xenical or any prescription drug. Once your blood sugar is leveled out you will not experience the cravings you probably do now. This is from a former compulsive overeater who spent years in OA etc. etc. on phen fen. It's all about your blood sugar. Once you get it under control you will be able to control your appetite without drugs.
