This morning I woke up with a bad hypo after 8 hours of sleep and a level before bed of 4.6 and that was more than 2 hours after eating an extremely low carb meal and having a stable blood glucose level for most of the day. This has never happened to me before - to wake up in the morning with a hypo. It's very concerning. I'm on day 3 of a low carb diet. Really not sure what is going on there but I'm really worried about it. The symptoms were really bad.
