In this form of diabetes diet, weight loss and exercise helps, but insulin is a necessity. Many people with Type I Diabetes are on continuous insulin pumps. This form of diabetes cannot be controlled the way that Type II Diabetes can be controlled.
I note in another thread that the OP had a head injury 7 months ago, but does not see doctors. Doctors are another necessity with Type I diabetes.
Metformin does not work with Type I. The OP would most likely need regular and/or long acting insulin.
