"started xenical 6 days ago. as i&#039;m a nightshift worker without bathroom conveniently available all the time i decided to start on days off &amp; with some fat in my diet to see how severe the consequences maybe. ate cheese salami &amp; crackers and took a pill..thinking the effects would follow soon.  some 12 hours later the oil / fat passed..&amp; for 6 days that has been my experience. i&#039;ve lost 2.1 kg so far i&#039;m really happy but have been really thirsty. which is o.k. not hungry though.."
