Sorry for the length of this...
I had a horrible experience with Metformin, so much that I had to stop taking it. Anything I ate would pass right through me so I'd have (sorry for the details) diarrhea everyday. It also gave me severe abdominal pain/cramping and made me nauseous as well. I lost 12 lbs in one week because I couldn't eat and if I did it would pass through me so quickly I probably had no time to absorb any nutrients. Not that losing 12 lbs isn't good but it wasn't in a healthy way.
My grandmother was diabetic and used to take Metformin for years but her stomach pain finally became so bothersome they told her to stop taking it and she felt better within days.
So first of all I would say maybe have them lower your dosage, Metformin is a very powerful drug and lots of people seem to have the same stomach issues with it. Look up apple cider vinegar and see what you think of it. Drinking raw apple cider vinegar every day (diluted in warm water) is supposed to cure many, many, many ailments and is said to be just as effective as Metformin for controlling glucose because it helps restore your blood to an alkaline state. I started taking it a week ago and noticed that my sugar/carb cravings have gone down dramatically. Give it a whirl. You get used to the smell after a few days.
Also, you may want to also consider experimenting with giving up ALL grains, legumes and dairy from your diet for a 21-30 days and see if that helps. Grains/legumes, even whole grains and gluten free, cause insulin resistance and contribute to gut and digestion issues. That means no breads, cereals, pastas, rice, potatoes, beans, peas, processed foods etc. Sounds extreme but after a couple weeks you feel an astounding difference. Try looking up a primal/paleo diet for more information about the lifestyle.
Good luck! I know how awful it is to have that discomfort, hope you can figure it out.
