Hi, Was started on metformin (1x500mg) daily on Thursday after my levels went up to 60. I also take 1 statin tablet each evening. I have always take my metformin with food. Have had the odd bout of nausea but today I am struggling with diarrhoea. I am due to increase to 2 metformin next week. Nurse suggested to start on one to limit side effects. Any advice?
