If you are female you may have polycystic ovary disease (I think that's what it's called...) or you could be pre-diabetic... How about calling his office and asking the nurse why you're on that med? He should have charted it. Tell her you are confused and if she can't explain it could she please have the doctor call you. You should know why you are taking this drug.
"People are like stained glass windows: They sparkle and shine when the sun's out, but when the darkness sets in, their true beauty is revealed only if there is light within."
