Those are high readings. But it's not an immediate emergency, so I wouldn't worry too much just now.
However, for the sake of your future health, you certainly don't want to make a habit of it.
Think about what you ate earlier in the evening. That will probably explain the high readings.
I've been insulin dependent for thirty years. But only relatively recently did I discover how to keep my blood-sugar near normal most of the time, and how to do that safely.
I certainly didn't make that discovery by following orthodox practice. The main elements are these: 1. When I take insulin; 2. What I eat; 3. Testing my blood-sugar a lot.
I have made quite a few posting on this Forum relating to my own management.
