Alli, is it working,if you are receiving none of the symptoms; however you are bloating and cramping horribly?

I already have had issued with my bowel functions...I tend to be unable to go for long periods of time. It causes cramping, bloating and a following over consumption of laxatives, diuretics, or diet pills...to try to rid the waste. I used to have an eating disorder, had it for many years (14 in fact...this is my 14th, but it is not as bad as it used to be). I started taking Alli lately, because I am weighing in the high 120's (5.41/2) and I can not stand it. It appears as though I have been losing weight since taking it; however at the same time, I am having none of the symptoms described on the bottle. I am instead becoming cramped and bloated, perhaps a slight increase in bowel functions, but since I rarely have one anyways, it is pretty much just an average, everyday function. So...it is working, and if so, how?
