I absolutely do not think about stuff like that before I sleep - I try to spend at least an hour winding down with a book and peppermint tea or something similar. I do however think about tough issues when I'm half asleep in the morning, reaching for the snooze button. (Sometimes it's counterproductive, making me want to snooze more to make the world go away, but I reach some surprising insights here - and then crystallise them in the shower, of course!)
