6 feet 3 inches, 155 pounds. I understand thin. I use the steel sets and I’m generally very happy; I don’t feel the thing hardly at all but I have to be very careful about where I place it. I don’t have any advice; only sharing that steel sets and the pump do work for me. I definitely have quicker BG lowering from the pump than an injection. If I started to exhibit what you are, I might place a set and wear the pump at night, to control my dawn phenomenon, then suspend it and remove it during the day and use MDI for my daily control. My morning numbers are dramatically better with the pump. Good luck, that’s a hard problem
