PCOS hormone changes?

I have PCOS, and am working with my Dr. to lose weight. I'm on medication, along with changed diet and exercise. I have lost 15 lbs and it seems as though my hormones may be adjusting I'm guessing, as my body is getting smaller. I'm just curious as to is this why I've been acting so crazy the past week and a half. I've been crying, happy, angry, and uncontrollably horney. Like I have been having sex with my husband EVERY night and when we're finished throughout the night once or twice doing it myself while I'm half way asleep. I'm just curious if anyone else has had this problem?
