I have a great doctor in Santa Ana and Irvine that prescribes it... I think it is $60 for a months supply. Dr. Alevizo's office and you can see any of the doctors. I used to go there but moved. Their number is 714-285-0800. They also have an office in Irvine so if you ask them they will give you the number for that office as well. My favorite Dr. is Kathy (forgot her last name) and she is super cool.... she won't restrict you from how much weight you want to lose.... being a woman she knows that everyone has their own goals. I found that the men would tell me I was thin enough... what do they know??
