I can't sleep. Again. My feet are too hot, or I want to switch sides, or my pillow isn't fluffy enough, or I can't sleep. In 5 hours I have to get up for my first day of lectures, but try telling that to my brain. Lying in bed, listening to what could either be the wind rattling my windows, or my flatmate's bed rattling the walls. It's a tough call. Possibly not helped by the pill-induced nap I took this afternoon.
