obesity
"I have been on orlistat for 2 weeks and already I have lost 10 lbs! It takes a few days to know what you can and can't have...trust me you will too! Ha! The only 'side effect' I've had was loose stools at quite short notice (but enough notice to get to the bathroom) and this was only because I had a small slice of birthday cake. Otherwise I haven't experienced any grim 'side effects' You definitely have to change your eating habits though. Looking forwards to my next lot off my doctor."
