metformin actually stops your liver from releasing its excess stores of glucose that are there for energy in times of need and also every morning b4 you get up to give you energy for the day. its possible your diabetes isnt that severe at this point and you maybe could take less metformin. you should track your sugars closely along with what you eat at what times and present your trackings to your doctor that will help see if theres a pattern and help determine your needs for meds
