Hi Although I have had a decent wight loss inmy first week of being on zenical 7 pound I am begining to think it is more because I am being so strict about what I eat than the tablet working I have had no side effects whatsoever nothing at all and if the tablets were stopping any fat being absorbed surely I would notice a different in the toilet area ( sorry to be so blunt) what has made me so unsure is the other night without realising it i hd abou 20g of fat in one meal and had not effects at all I also have ben sprinkling parmasan cheese on my chilli again with no effects at all Is it possible I am taking these tablets and they are not doing what they are suppose to? I am almost tempted to have something really fatty to test it? I hear of all these people who have dreadful side effects just because they ate a bit of chocolate or something and i just seem to be exactly the same and I know its the worry of the tablet side effects that was keeping me on the straight and narrow now I am losing faith please advise anyone ???
