Discuss with your: Doctor. You may need to see a dietician to help avoid the high and low bs levels. Not knowing your history makes it difficult to comment on the medications each patient is different.

Do not be afraid: Metformin does not cause hypoglycemia or low blood sugars. It is not insulin. The drug can sometimes cause GI side effects like nausea usually transient. Lactic acidosis can be a medical emergency doctors tend to start metformin as first line therapy for early stages of Insulin resistance, diabetes or when life style modifications have failed to control the sugar the glucose levels.
