They do provide a great service if you know what you are getting into, but they do not do a detailed medical check on you or ask a lot of questions. If you have any doubts, talk to your own doctor before going or go on line and do some research. On Saturdays, the lobby is packed and they are pushing people through at an incredible rate. They barely look over your medical history - it's more like they are just covering themselves in case there are complications. However, if you do the homework up front and make sure that you can take the stuff, it works. But you have to be responsible and take yourself off after four months - they won't.
Pros: Helps jump start diets
Cons: May not check your medical history enough
