Metformin reaction

It should not do you any damage to stop the tablets to get some relief - they aren't a glucose lowering medication, and if you do react badly so swiftly then it probably will only get worse if you go on with them. My own experience was dreadful, with pains in my muscles and joints, and it was the worst couple of months I have had.
Your doctor might prescribe the same medication in a slow release form, or it you are really lucky will allow you to try low carb eating - most doctors are dead against it, but for the lucky ones it makes diabetes irrelevant.

When I started Metformin a got similar symptoms for around a week. I’m now on 3 x 500mg a day and tolerate it very well, no side effects at all

Hi this is my first day on metformin 500mg and what you say terrifies me if I get any of those symptoms I will stop taking them as before taking the tablets I felt fine no issues at all am trying to get my head around being diabetic.
