Metformin and dry mouth Hi, Started my Metformin over a week ago and up to know no dreaded stomach problems to report (hope not tempting fate here..??). Anyway, the only real side effect I have developed in the last few days is a very dry mouth / throat which is causing me to drink more than usual. Prior to dignoisis of T2, which was only two weeks ago I never suffered from the classic signs such as raging thirst, weight loss etc. However since on the meds I am more inclined to feel thirsty. I have read that this can be a common side effect and should ease, however anyone else found this a problem? I suppose out of the side effects some people report I should be lucky.....better to spend time at the tap in the kitchen getting a drink...against time in the loo..!!
