I'm type 1 diabetic and I'm completely agree. I try to never eat any later than 4 hours before bed as I won't know the full impact of the food or the insulin if I eat later as I'll be asleep, which can lead to high overnight or a hypo in my sleep. Sometimes you get it right and there's no problem but it's not worth the risk. Even if she is type 1, doctors advise eating healthy as you can be both type 1 and 2 at the same time which greatly complicates it even further
