I’ve had two incidents recently of extremely low blood sugar. I woke up in the morning and checked my blood sugar - it was around 170. I was going out and not hungry yet, so I decided not to eat or take insulin until I got home. 30 minutes later I felt like I was going to pass out, I checked my blood sugar again and it read 28. This is the second time this has happened with no explanation and I would like to prevent it from happening again if possible. Any ideas??
