Ouch man, I hear you. While I can't totally relate, I was on metformin (generic for glucophage), and I wasn't properly tested for diabetes, so it ****ed me up (especially since I was on 500mg twice a day). I would pass out a lot, and my glucose levels would be around the 45 ~ 60 range, combined with really bad heart burn, it was the worst pains I've ever experienced.
So yeah, I can definitely sympathize. I'm glad the medication helps, but take it easy, alright? I really hope the weather gets much better for you soon!
