How to Sleep Better

I generally switch off about 10 o'clock, so no one can contact me anymore. I drink a lot now in France, but in England, I drink a shitload of tea. The thing about coffee, which I've never understood, is that people drink it literally just before going to bed. Like, when you go out for dinner here, everyone has the dinner and then they say, do you want a coffee? And I think, well, no, it's like 11 o'clock at night. Yeah, but it helps you digest your food.
