I just keep thinking, Lisa, that he will adjust to the higher dose and generally lower his overall numbers. It's frustrating that he throws the low nadirs that can mean a dose reduction. I know you aren't home during the whole cycle so the low nadirs are troubling. I do wish you could try to feed them - higher carb to bring up a number in the 40s and below - and see if he would eventually settle into the dose.
And not sure how a low nadir would impact your present thought to do 13/11. Maybe just a touch lower for the one dose?
I am sure this is frustrating. He seems so close!
