Hi Ozziemum, welcome to the forum! I don't take metformin myself, but I know that this is a very common side effect. With most people I believe that the problem settles down after a week or two. If not, there is an alternative 'slow-release' version of the drug which has proved better for those not suited to the ordinary stuff. The ordinary version is cheaper, so this is probably whyt your doctor has asked you to stick with it for now, to see if the side-effects ease after a couple of weeks - which I hope it does for you!🙂
