Unfortunately because I live in New Zealand for a global company I often have meetings in the middle of the night so the no computer before sleep is tough, I'm also worked up after those meetings and usually need to wind down somehow.
I do try and do most of the above, including no coffee after 12 (which is tough because I love coffee).
It will get better at some point, we're just delivering a lot of projects in Europe but attention will shift to this part of the world next. But if it doesn't look like it will improve I'll probably look for something else when the current set of products are in market.
I also choose to have meetings at night, work would happily pay for me to fly to Europe but I try and avoid flights when bluejeans will suffice for environmental reasons.
