Not an answer to your question, but just a general comment. I would not start a new pump I had never tried before at 11:30 at night. In fact, I wouldn’t start anything new at night. By that I mean new basal insulin I had never used, new type of CGM I had never used, pump I had never used…
A general suggestion for anyone I would make is to start something different and totally new in the morning so you can keep an eye on your BG.
