It may not work for all of course but my insomnia (undiagnosed, so whatever the sleeplessness actually was if not insomnia) has almost completely gone after I started meditating.

Now I don't mean sitting cross legged while chanting "ahhhh" or anything like that, just give your brain an hour or so daily to start but you can probably drop to less after a while (I do it every 2-3 days now).

My best guess it's like freeing up some CPU time for garbage collection. With having podcasts, videos, films, computering, etc going almost every waking hour the brain never really gets a chance to filter through all of this stuff so attempts to do so the only quiet moment it gets - right when you're trying to fall asleep.

YMMV, Works For Me(tm), etc. Good luck!
