Okay I've been taking Xenical for one week. So far the side effects are not as bad as I thought they would be. The first day I was afraid to leave home, but no problems. I have had some greasy foods, like scarfing pizza yesterday

and it does mess with the stomache. I haven't lost any weight yet, but I did not expect to so I'm okay so far. I read an article that said Xenical takes approximately 600 calories out of your diet every day. That's a little over a pound a week, so it is not a quick fix. I'll keep you updated.
