Hi Murray,
I also took
Glucophage but for a fertility issue. It made me incredibly nauseous every day and they had to lessen my dose. I am sensitive to medication but my fertility doc said that it has that effect on a lot of patients.
I will tell you this, if I didn't eat any sugar or carbs it was a lot better. Try cutting down to begin with and if you do get nauseous maybe try cutting back even more.
It really helped my PCOS, which I also suffer from, so I was able to have a baby so in my opinion it was worth it. I had a "no morning sickness pregnancy" so I guess it was all fair!
Good Luck
