Yeah Ceebs, Meridia is an SSRI. Xenical is the one that can cause oily and uncontrolled leaky stools. Meridia decreases appetite in some overweight or obese folks (but not all). I have no idea if it has the same effect in non-obese people, and I haven't tried it. Keep in mind also that drugs like Meridia seem to have little impact on long term weight loss, but they appear to help some people acheive short term weight loss.....
