If you take metformin, no more than 2 pills a day depending on the mgs. Then again if you are diabetic then its a differnet story. Most diabetics take one to two pills a day depending is they are type 1 or type 2.
you will see changes in your body because the pills themslves shut down your sugar craving. Carefull to not bring your sugar level to low, if you are not diabetic though, your pancreas does its own thing in releasing glucose for energy.
