Substitue for Metformin?

Hi ladies... I was on 500mg metformin and it did great things for me. TREMENDOUSLY helped with my cravings (they were sooo bad before, I had to have something sweet or I felt I was going crazy if I didn’t), it helped with darkness on my armpits and inner thighs, and it just helped my appetite over all. Although it did so much good, the bad outweighed the good. My diarrhea was terrible and it never went away. Not even after a month. It was so bad I couldn’t even go out anymore. After a month, I went back to the drs and he lowered me to 250mg and prescribed extended release. The diarrhea was still there and I gave it a few weeks but it never went away so I just had to completely stop using it and never went back to the drs. I tried taking it at night, lowering my carbs, but nothing helped with the diarrhea. Honestly Im just over the diarrhea and don’t wish to go back to it but I do miss all the good it did for me.

Soo my question is, is there something else I could take instead of metformin? Or something I could do differently? I will be going back to the doctors just wanna have some insight on yalls experiences
