Hmm unless you are struggling with your calories, then I'm not sure how the duromine would help you because it would just help you lower your calories even further but I wouldn't recommend that based on your current caloric intake.
I personally had a period of 3 months one time where I was exercising almost every day, eating right, etc and didn't lose anything. I actually ended up going on vacation, doing different exercise, eating what I wanted and then I came back and lost weight and kept losing it.
Maybe you need to just shake things up a bit to get your body kick started.
You can't out-exercise poor eating habits.
