"i&#039;m on my second month, and or bottle of alli. i tried it in the past, but i must admit, i ate fat and yes, had the loose bowel motion, but didn&#039;t gain weight. no i only had 15 lb to loose, and so far i&#039;ve lost 7-9 lbs in a month, eating good. i did go on a week vacation and ate cake, drank cocktails, ribs, etc.  not every day, and yes it came right out. don&#039;t laugh, but i didn&#039;t gain a pound during the week. i&#039;m not using it for that reason, but hey, now you can go on that cruise during your diet and not gait weight. ya, you go to the bathroom a lot, but you know its all coming-out. for the most part &#039;im 90 percent on track, with no side effects. and if i eat pizza and nachos on friday night, so what, i don&#039;t gain weight and for once i&#039;m not constipated."
