Can’t get it to 90 when I wake up. Help?

My endo said she wants me at 90 when I wake up. I’m on ControlIQ on the pump and the range (which can’t be changed) in sleep mode is 112-120. If I’m 100 before bed, I issue a mini correction but then have several lows through the night. My body reacts to the lows and then it ends up at 150. Usually it comes down and I wake up around 115 or sometimes 100 if I’m lucky…. Sometimes higher.

How is this even possible? Any tips?
