so with you on the staying up late thing.... drives me nuts!!!! (literally) I tried telling him all about sleep wake cycles etc... didn't do a thing, lately I'll tell him when I'm going to bed, and then a bit later I'll ask him (nicely) to come to bed coz I can't sleep (please) and it works heaps better. I think he feels like he is being nice to me rather than doing something he has to do...
My hubby actively avoids learning anything about BP, he is a doctor but knows less than most of my friends, I also printed of info, I have stacks of books... but nothing..
