That is what my doctor gave me when he said I had type 2 diabetes was metformin 500 mg two times a day. Man did it make me so sick. Bad pain in my upper stomach and real bad diarrhea I could not go any where because of the diarrhea. So now I am on Novolog mix 70/30 Januvia 100mg Glipizde. Now I,m doing good you may have to change the medicine. A lot people have a lot of trouble with the metformin because of the side effects. Wish you luck.

blood sugar dipping to low will cause you to be dizzy test your blood sugar if it is low eat a snack you should eat a healthy snack between meals and before bedtime.

After 20 years on Metformin the last dosage was 750mg 3x per day my doctor took me off metformin due to bad kidneys. Now on 2 types of insulin

I was on metformin 500 mg also when I got very sick and had to go to hospital because I had severe diarrhea which depleted calcium, magnesium and potassium. I take Lantus Solarstar, Januvia 100mg and Glipizide. I am still trying to get the right doses to control sugar.
