Day 2:Essential for reading in bed without disturbing whoever you happen to be sharing a room with: a mini clip-on reading lamp. I got one of these a few weeks ago, and it is so good for when my roommate wants to sleep and I can't tear myself away from my book (which happens quite a bit). I used to use a torch, and I'd have to hold it between my neck and my shoulder. Very annoying.
But these are really good. They come in tons of different colours, and there are loads of different designs around at the moment, so you have a lot of choice.
