Metformin Hydrochloride and glumetza

I've been on Glumetza for about 4 weeks and I sweat all day long! I thought it was just our hot days in August, but I can sit in an air conditioned room and still be drenched. I only take 500 mg. at night. and I used to only perspire heavily after my morning coffee. Now, it's all day.

Does anyone else have this problem? Please let me know/

If someone can answer this question for me that would be very appreciated.

1. Does this med cause weight gain?
2. Does this Poloystic Hormon Syndrome ever cure, does is cause infertility?
I'm trying to have a child, and i'm concerned about that issue.

The only side affect i have was diarrhea.....It hasn't continued, but sometimes a little gas.
