If you're on the MM CGM and it's less than 30 days since you started, and you are finding it to be a royal pain in the @$$, then please consider returning it and getting full refund. Go for the Dexcom 7+ CGM instead. It's the easiest and most accurate CGM available...and you'll really like it.
I used to be on the MM CGM and was extremely disappointed by its performance and the pain it causes upon insertion, and the gaping holes it left in my body upon removal. Thankfully, I was reading up CGM posts in the forum and switched to Dexcom 7+. The difference was like night and day.
