Let me tell you about Xenical. Even if it were OTC I would not take it. The side effects are awful. Well, I guess they are not side effects. Yes, Xenical blocks fat from being absorbed, BUT once the fat has been blocked in the GI tract, it come out like a rocket! If a fatty meal is eaten, people experience explosive diarrhea, runny loose stool, nasty ass gas etc. This is how the drug works. The thing is, it can't tell a healthy fat from a bad fat. I you suppliment with Fish Oil, almonds, flax, eat red meat etc. BOOOOOOM! It has its place in the Rx community. It can really change the way people eat. People eat low fat to avoid the SE. I don't know, i wouldn't mess with it, but thats just me...
