Metformin
"Hey OP sorry I didn't read through the thread so not sure if anyone mentioned this but I used to take regular metformin 500mg 2x per day but like you I would be on and off cause it literally made me so sick and tired. But recently my new doctor recommended metformin extended release. I swear it's been a life changer for me. I take 500 mg per day and I've been losing weight and it doesn't make me feel sick at all! I've also been taking biotin simultaneously which has increased my overall mood and energy, not to mention my hair and nails have been growing too!"
