So i was prescribed 2000mgs a day in Nov 2017 ive lost 12kgs and about 12cm off my waist my specialist was happy with results and said my period should come as the weight come off. I havnt had my sugars tested or anything to know if the Metformin is actually working right and im also wondering could i be having too much and could too much be contributing to no period??!
