Loud techno music! Right now, I'm listening to a mix of Moby, Fatboy Slim, the Prodigy etc :o)
Seriously, though, I had that same problem when I was in university.. I couldn't concentrate at all when I was in the labs in the mornings, but I found I used to work much better at home.. so, my solution was to come in late, spend mornings at home... sometimes, though, you just need to relax, or think about/do something else to help regain your focus.. walks and a break near the coffee maker help for me.. :o), also play tetris or minesweeper (yes, I own up to it ;o)
