I bought some Alli a couple of weeks ago and only managed to take them for a couple of days. They didnt make me go to the toilet more, in fact they constipated me and made my stomach make the weirdest noises! I started SW last week and actually have not thought about re-starting the Alli. Maybe if I have a weight loss stall I will consider it. The problem is you have to eat below a certain percentage of fat while taking Alli, and although on SW my fat intake has lowered, I cant be sure its low enough to be taking the tablets. The side effects if you eat too much fat while on them are supposed to be very unpleasant!
