Hi Adam 🙂 Yes, I totally get what you are saying. I have always lived alone and have been diagnosed for 12 years now. Although my control has been pretty good over the years there was always that subconscious anxiety about the possibility of a night hypo, so I always tried to make sure that I was at a comfortable level before bed, and, importantly, that my evening meal insulin had had time to fully expire before going to bed - despite the 'rapid' or 'fast' name attached to bolus insulin it can actually take up to 5 hours to fully expire, so if you go to bed 3 hours after eating/injecting then it could still have the capability to drop you lower for another two hours. This, of course, can vary from person to person. If I was, say, 5.0 before bed then I would eat a slice of bread and peanut butter to help keep my levels elevated overnight, and I would frequently test in the middle of the night if I had to get up for the loo 🙂
If you wake in the 7s or 8s, it's not a worry, it's more important to stay safe in my opinion, especially in the early weeks and months after diagnosis 🙂 In time, you build up experience and knowledge of how your body reacts to your background insulin, food you have eaten, the effects of exercise during the day etc. As long as you can maintain good levels during the day, running a little higher overnight will not have a significant impact, and you will fine tune things as time goes on 🙂
I'm particularly aware of how living alone can make you a little more anxious, even if it's subconsciously, because it emerged that I'm a Type Weird rather than Type 1 - after 4 years I stopped needing a background insulin, and I remember very well the feeling that a little stress had been lifted from me, so I can fully appreciate the contrast 🙂
