I ran into the same problem - hit the plateau and wandered all over it for about 2 months. I contacted my surgeon and he prescribed Phentermine and it has done the trick. I lost 8 pounds in the first 6 days taking it. If you have high blood pressure, any history of addiction, etc. your doctor may not rescribe it - and some doctors will not prescribe it at all. Good luck!
pcos may cause weight regain
try meridia or phentermine if you think you are eating the right sort of diet and yet need to curb your appetite
good luck
