Lantus to Basaglar?

Hey, y’all! I’m a type 1 diabetic and my health insurance recently switched so my endo switched me to Basaglar. I had previously been using Lantus.

I was told the dosing is the same, so I haven’t changed my dose, and I dose at 8:45pm every night. Since the switch, my blood sugar has been dropping around 10:30/11, often going into low territory. I treat with a juice box or something similar (I don’t overtreat), but then wake up high and typically remain above 200 during the day.

I’m wondering if any of y’all have experienced this? I’m going to call my endo, and I have an appointment coming up, but wanted to see if the community had any insight.

Thanks!
