Planning to go for a doctor visit for their "weight loss program"?

Please help! I want more information before I go to visit my doctor and have to pay $85 for my first visit.I was told that my first consultation visit is $85 and from there on my additional visits are $50.What does this mean?I think my doctor just wants to monitor me because I hear there can be different problems caused by taking those phentermine pills, or "Adipex".Will my doctor give me an inexpensive prescription for these pills, will she have samples to try out first?How much do these pills normally run when a doctor prescribes them?Also, I have insurance, does it even not help for the pills?What can I expect out of all this?I really want to do it because I want to lose weight!I am currently 23 ,5'3 and weigh around 165 lbs.I have a hard time not eating what I like.I exercise daily.What are the additional visits to the doctor for?
