From the looks of your profile, you dont have all that much weight to lose. The last few pounds are harder, but if you persevere they will fall! I agree, exercise should help. So might switching meds. There could also be something in your daily diet that is causing a stall. Why not post some sample menus under "journal/bootcamp" to give us some idea of what you're eating every day?

Hang in there!
