I've found the best way to handle my sleep problems was switching to a polyphasic one - where I'd have a small "core" period (3-4 hours) and then 1-2 short naps (30m - 1hr) throughout the day.

I'm lucky in that I do freelance from home so I have that flexibility.

It's pretty great overall, though, because I'm feeling refreshed, I'm not fighting off sleep, but I'm also not forcing it, either. It basically lets my body rest when it needs to rather than laying in bed, endlessly tossing & turning or worrying (even without anything distracting).

As far as the post goes -- all great suggestions! These do definitely help especially with just getting into the habit of not messing with any tech after a certain time.
