3rd week on Metformin. Week 1 Started at 250mg with Meal 1, Added 250mg with Meal 3 on week 2 & added 250mg with last meal (No Carbs. Cucumber and Chicken Only) on week 3. So, now at 750mg daily. I checked fasted blood sugar today. It's low at 65mg/dl. (Ref. Range 70-110 mg/dl) Before starting Metformin it used to be between 92-98. I was about to add another 250mg starting week 4 today but did not after seeing this reading. Also my plan beginning was to take it to 1500mg daily over the weeks. Should I be concerned? What are your FBS readings on Metformin guys?
