Hey Nicki,
As someone with PCOS, I do sympathize...but disagree that PCOS makes weight loss via healthy diet and exercise impossible. It makes it a bit harder, it means you have to be a bit more committed to making healthy choices every day, but it definitely is possible. I lost my weight with nothing but a mostly-whole-foods, calorie counting plan combined with lots of exercise. So it isn't unattainable or even nearly so...there are many people here with PCOS who have attained weight loss using only those methods.
Adipex is the same as Phentermine, so please see our thread here:

Adipex or other meds
There are different forms of PCOS, some have high testosterone and some are insulin resistant, which is my problem. I can gain 8 pounds in a week, while dieting, it's very frustrating. Docs have put me on diabetic drugs, even though I'm not, to see if it will help.. which all it did was make me sick. Their theory behind my weight, and the problems loosing it, all seems to be tied into PCOS and the insulin resistance. At least that's what they're saying this week!
