I recently read a news article about a 57 year old woman taking Metformin and it triggered hot flashes, nnight sweats, nausea, stomach pains and dyrreha. My PG doubled my Metformin from 1000 up to 2000 mg per day 6 weeks ago, and I am suffering the same symptoms, at age 75... When I told her, the recommendation was to cut the tablet into 4ths & take it 4x/day. Would you have a better solution?
