How much weight do you lose in 6 months pre op?

Wow you only lost 7 lbs with meridia? Well I have to take a month off phentermine and he put me on TENUATE for a month then I will be put back on the phentermine. He requires to take a break from phentermine every 3 to 4 months. He either gives nothing or will give you this other med. Never heard of it before. But i am waiting for a prior auth for it. They had to do it with the phentermine but now have to cancel that one and then next month do a new prior auth for phentermine.

Has anyone try the tenuate? I like the phentermine but i heard it can poop out on you as well when you been taking longer than 3 months.
