I am going through PoE 2 right now, so I think about designing a multiclass only party before falling asleep. Sometimes I also think about how I would improve a game. I try to keep it as light as possible.
A trick I learned some time ago is to switch off all watches somewhere around 8 PM. I used to have difficulties sleeping, so realizing that it's already 2 AM and having to wake up at 6 would cause further stress. Now, I only go to bed when I'm sleepy and I know that it will take a brief time to shut off. In the morning I don't know whether I slept for 5 or 9 hours and it all feels the same before coffee. When I later check my browsing history, sometimes I'm surprised that I'm so tired despite sleeping so much, and sometimes it's weird that I'm full of energy even though I played late in to the night.
