Anorex (leptoprin)

This is my first post and I would like someone's advice. I am very overweight and have started swimming four times per week and watching what I eat. It has been slow but I have lost 40 lbs. Since september 2003. I gained 4.5 lbs back over the holidays and have started again but it's difficult (as usual). Does anyone know anything about anorex (leptoprin)??? I have tried to get information on the internet about it and may not be looking in the right places. I have gotten a little info about it, along with pros/cons but mostly got info on how to buy it. Please help if you know anything about this product or can tell me where I can look for myself. Also, do you think it's harmful?? I don't want to risk a stroke or heart attack if it's really a main "factor" with this medication. Please help!!!!!!!

thanks much,
