This is where you get into issues of trying to determine just what made a change. Was it the EO, the meds, the diet change, or a combination of both.
I always TRY to limit to one variable, at least for about a week, to determine what made me better. I hate when Dr. asks me to change amount of both types of insulin, AND adjust eating/timing, along with exercise. Well, any of those could have made for better glucose control
