I gave it about 15 months. I fought with the CDE at my drs office and with Medtronic about the rates and changing the AIT because I was consistently running hyper at least 25-40% of the time, despite giving phantom carb boluses and corrections like in Sugar Surfing.
I turned it off last night and woke up with a blood glucose level of 85. I’m running better today than I have in a long time. I think I need to stick to basal rates until a more aggressive algorithm comes along. I fought the good fight and am in need of a break.
