Sleep habits.

I found an article online about re-setting your sleep patterns. 

I’ve tried this myself, repeatedly – it’s a great way to re-set. I still struggle with insomnia sometimes, and this routine is what I follow when it all gets out of whack. The thing I’d add is that I make sure I’m properly hydrated before going to sleep – typically by drinking a pint of water half an hour before I go to sleep.
