Hi there,
A friend of mine was on Meridia and was not too thrilled with it. Not only is it very expensive, but she did not lose much weight. She is about 100 pounds over weight and lost pretty quickly in the first few weeks, but then it just stopped. I am taking Adipex-P 37.5 mg and it works great for me. It makes me a little jittery, but I space them out every other day. It is around $46 for generic but I have lost 43 pounds in about 6 months. It gives me energy that's for sure but I have to take it early so I am not up all night. All I can say is it helped me a lot and my doctor is very leary of all diet meds and he prescribed it. So I guess it's "safe" Just my 2 cents.
