Just a warning about so called cheat days... i had an awful day yesterday and went out to dinner and ate all sorts of crud... i knew ahead of time i was going to do this and didn't take ANY alli pills yesterday... and this morning i had a very minor incident... my first alli opps... to be blunt, i felt the need to fart, did so, and a tiny bit of greasy stuff came out when i did.. i immediently went to the bathroom and finished my business, mostly normal looking, but def big orangey droplets of grease too... sorry to be so discriptive, but wanted to let everyone know to be careful when "cheating" even if you dont take any pills that day.. i think it must stay in your system at least a little bit. i learned my lesson and hopefully got at least some of my "cheating" out of the way. at least now i know it actually works! before this i hadn't seen any symptoms or treatment effects in the least! good luck everyone on reaching your goals!
