I am on day 5 with my MM CGMS and I have had a migraine for almost two days straight. My average used to be around 200 and now I've been able to keep it around 80. I am thinking that it is because my body isn't used to being in this range for long periods of time. Has anyone else experienced headaches as a result of better blood sugars? Is this something I should worry about? Does it go away?
