My doctor has prescribed me Xenical

Two words - anal leakage.

Is that the stuff that makes you poop your pants?

It's not actually poop. From what I understand it's liquid fat seeping out of your *kitten* because xenical stops your body absorbing fat from the food you eat. In any event, it's about as sexy as it sounds.

Hi ya, I've just recently stopped taking it having been on it since November. I found that it really made me question what I put in my mouth as if you eat over the recommended fat allowance for food and per meal then be prepared to end up with unpleasant toilet issues. It is known as the tango effect as it will cause loose orange deposits due to the fat it expels. Can be difficult to flush as fat floats and you may find you do leak particularly if you have eaten very badly. If you stick to what is recommended then you will be fine. I've only come off it now as I feel I've finally got control of my eating where I don't need the threat of the terrible happening. I had to yo monthly to have my weight checked at the gps as they would only give it if you were showing to be losing weight on it. Had a target amount of 5% loss in the first three months and a further 5% by six months. Think these could be standard targets. I had gone to docs as I was considering surgery and being on this for a period of time was a requirement for me. Having done it now and learned some things along the way I now no longer feel like I need surgery and this medication has definitely helped me take control of what I was doing to myself.

But... fat is good. Fat isn't what is making you gain weight or hold on to weight. It's a simple issue of eating too many calories. So I don't see how this will really help since you won't be learning anything besides to stay away from fat. Which is dumb to do.
