I've been gradually increased from metformin 500mg at bedtime up to 500mg at breakfast and 1,000mg at breakfast. It's been a month since I first started metformin and my fasting number still isn't below 110. My doctor just keeps increasing metformin and it doesn't seem to be doing anything. My after meal numbers are always in goal under 130 so I can control that with diet but nothing I can do for fasting sugar.I eat dinner no later than 6:30 and take metformin at 9 when I wake at 6 it's 110-120. I'm 31 weeks and my baby is already 4lbs. Am I overreacting by saying "Quit screwing around and just give me insulin"?
