"i honestly can&#039;t remember how long i&#039;ve been on xenical , about close to two months i&#039;m guessing. i&#039;ve had the oily poo but it does depend on what i eat. i haven&#039;t been exercising but i know i&#039;ve lost some weight. i&#039;m just too scared to check how much. from tomorrow i&#039;m going to make sure that i&#039;m walking more and exercising as well."
