SilverK, I'm not and never have been an insulin user, but what I have seen suggested in similar circumstances is that whatever you decide to do before bed, that you set an alarm a couple of hours in, to wake and test your bloods, to see what has happened.
Obviously, this isn't a strategy you'd want to be doing every night (!!), but maybe whilst you're really getting to understand how insulin is working for you and the impacts of various things, it could be very useful.
If you can afford it, it could be really useful to invest in one or two Libre sensors, so that you could see what happens to your blood glucose 24/7 for a couple of weeks (for each sensor). That could give you a really useful insight.
The Libre sensors are c£50 a shot, plus you'd need a compatible phone, or a reader (at another c£50) to be able to access the data, but I deliberately chose to use the word investment, as in your shoes, I might be inclined to see it that way.
Of course, it isn't for everyone, but something to consider if the coffers can stand it.
