Can't say one way or the other about the meds, i don't use this stuff... Only had the metformin and the glic for a while there, the other never came up. Personally, I'd think they'd up the met if it's Dawn Phenomenon that's the problem. It is a problem? How are your numbers at the moment? The morning numbers are the last to come down as the liver's stores are depleted.... Are you still running high? What are you eating?
I seem to remember you wanted to try low carb, did that work out at all?
