luvmyfam, I don't have much experience with dealing with PCOS. I'm not, as far as I know, actually PCOS. I just have some PCO tendencies and my pretesting came back with indications of IR so the Met is more of a precautionary thing for me. I also have family history of diabetes and IR, but not PCOS to my knowledge. I've never been anovulatory, had any odd hair growth, or other high testosterone symptoms. Mostly it seems my issues is more IR related and Met is a diabetes drug.
I had to titrate up really slowly to get to 1500mg, something like 3 weeks, and was sick as a dog for a few weeks. But after suffering through that I tolerate my dose very well now.
Maybe if you can't get above 1000mg you should just take what you can tolerate? Especially as you aren't really needing the Met, even a lower dose would help sway pink for you. Though there's no point in forcing the issue and it's excellent news that your labs all look good!
