I was honestly dreading this method because I am personally not into meditating. I've tried it, and for me, it's always a fail. (I know I sound very pessimistic, but I'm trying to be realistic with myself here.)
I knew I'd likely need some help here, so I downloaded the ~trendy~ meditating app Headspace and followed one of their night meditations. It definitely helped relax me, but I struggled with keeping my mind clear once the session ended.
Afterward, I laid in bed wide awake, trying my best to fall asleep, but my mind was all over the place thinking of the next day's work, my morning coffee, and whether I should sign up for that early morning Barry's class or not. After about an hour and a half and a lot of tossing and turning, I finally fell asleep.
