Hi all. I started Metformin immediate release 16 days ago - Saturday just gone I went up to 3 a day. However right from the start I have been experiencing nausea, diarrhea and a sore stomach and feeling generally unwell. I have to be well for a training course tomorrow so have stopped the med this lunchtime. I have rung the doctors but can't get a telephone call with the diabetic nurse or a doctor until Thursday. Is this usual? I feel totally unsupported. I had a very serious depressive illness from which I thought I had recovered but this trouble is really upsetting me - I just feel so unwell now. Can anyone relate or offer any advice?
