Metformin Hydrochloride and stomach pains

I was on 500 mg/ twice a day to start off with for PCOS and was trying to get pregnant. However I was never able to get past the 500 mg/ twice a day as for the side effects were terrible I had severe nausea and vomiting every day all day long and couldn't keep nothing down (when I could eat) which lead to having stomach pains. I stopped taking it as for the side effects were way to severe for me to deal with.

Metformin has been giving me a serious problem for 2 months. Every time I take it I get really bad pains in my lower back (on the side). I do not know if this is effecting my kidneys or what. Last week I did not take Metformin at all and the pain went away but the sugar went up. Starting tomorrow I will no longer take it. My answer to metformin is a larger dose of Lantus to keep the sugar down. Side effects were, back pain, stomach pains, nausea, bloating, tired, unable to walk, trouble working (cleaning carpets. If you are having similar problems try not taking it for a few days, if the pain goes away...never take this medicine again. It is doing more harm than good and there are other options out there for you. My answer is more insulin. Good luck
