I was on Xenical about 6 years ago, yes it works, and I guess the most memorable things it taught me was to read labels.....FAT grams in particular.
It keeps you honest about what you are eating, it's not a license to eat and just block part of the fat calories...if you consume a meal that is high in fat, (example; fettuchini alfedo, bread and butter, fried chicken)...the Xenical will react within 30 mins....33% of the fat you are NOT ingesting will be expelled in the bathroom. and it looks/feels like a whole lot more.
With diet/exercise and Xenical I was able to lose wt. easier, but everyone is different....as a rule, I'm one of those people who has to work for every ounce I lose.
