How did I live without them? I'm in the fetal position and and my room is pretty much pitch black and I forgot how I missed sleeping in a dark room. Is it possible they make the room quieter too? No? It just never gets all-the-way dark outside here. We'll have to see if I actually have more productive/consistent sleep. Call me an optimist. It's 4 PM and I want to go to bed.
I bet people that don't have them think "there's nothing wrong. Why would I need them?" and I say it's like discovering ice cream as a 30 year-old. They are just that good.
