For Weight Loss (Obesity/Overweight) "I have used Alli for approximately 4 years to control weight from getting worse. I depend on it being diabetic, and it has now been recalled. I take up to 4 x 5-pill servings of high-quality fiber, but without the Alli, I am having a horrifying time with bowel movements and rectal bleeding. The bleeding was going on while taking Alli but is worse without. I know there have to be others like me that need to relate as well, and that is positive!"

For Weight Loss (Obesity/Overweight) "The side effects were not worth any potential weight loss. I spent way too much time on the toilet. I wasn't even having bowel movements. I would sit there and 'oil' for hours. I had accidents and 'oiled' myself with this nasty orange oil. I'd rather be a fat cow than have accidents in my pants."

For Weight Loss (Obesity/Overweight) "Xenical really helped me, but some of the bowel problems I had made it marginal. I was hit by all the side effects."
