I was awake at 4am too Rose, massive problems with new hayfever treatment mean I wake up at 3.30am/4am with completely blocked sinuses and a raging thirst - hideous, isn't it, being awake then? Esp when I have to get up at 6.30am groan....I'm taking extra Vitamin B complex tablets early afternoon, to get a bit of energy - and they do help.
Hope the reading is going well. When I was at uni I would go to the library, pick a desk as far away from the books as possible and then play a prevaricating game called "Make up the title of those books over there" . Then, in order to be academically precise, I'd have to get up and go and check - and at the same time, spy on the guy I fancied who worked at the cafe....happy days
