Adios is good, or so i assume, my friend is taking adios while on her WW plan for the last 9 weeks, an has lost an average of 1/2 pounds extra per week, its 10 pound for 100 tablets, u take it with your meal up to 4 tablets a day, they are herbal. V good. im taking them now too. Have a read about them. Allie is similar to Orlistat (given on prescription bu the doctor) gets rid of excess fat in the body and comes out via the other end, however it comes out orange and stains everything its truly awful, i had them a few years ago an didnt take them again x
