It HAS to be freezing in the room, and I keep a fan on my night table that has to be blowing right on me, and I need my down comforter, and two pillows (one super fluffy, one medium fluffy), and lip balm within reach, and it has to be completely dark, and I have to be on the right side (facing the bed) of the bed. And no ticking clocks anywhere near me. That drives me nuts.
I am definitely a high maintenance sleeper!
