This started about 5 years ago. I started watching YouTube on my tablet in bed before going to sleep. Now I can't not watch a video before falling asleep. I wake up multiple times in the night and have to listen to a video (I use earphones and don't look at the screen) otherwise I just lie there and my mind starts worrying about stuff. I usually listen to something like a documentary and fall asleep again. I can't seem to stop doing it. Wtf is wrong with me.
