I've been sleeping better at night and taking naps again after getting off a med that was causing partial insomnia. Last night was kinda rough and after exhausting all my music and other things I finally turned on a 2 hour brown noise and then I fell asleep pretty much instantly and I woke up past the 2 hours with no idea where I was, what year it was, or basically who I even was. Idk but it seemed to work as good as a sleeping pill. I'd only save it for emergencys myself. I've had good luck using brown noise before. Way better than white noise or rainforest sounds.
