I am surviving today on caffeine.  By the time I turned off the computer, it was 2.45am.  By the time I settled down, it was probably 3am.  Woke up at 3.30am.  Woke up at 5.30am.  Woke up at 6.15am.  Felt *exhausted* when I had to get up at 7.10am.
Too cold to buy a coke, so I bought a small cafe mocha from Gloria Jeans.  It's the only coffee I can drink without getting very nauseated (although it still makes me a little queasy).  I've had half, and I'll try to save the rest for lunch.  
(I'm kinda sensitive to caffeine.  If I drink it all now, in half an hour, I'll end up so hyped my hands will shake.  I kid you not.  It happened last time I drank one, and lasted for about forty minutes of trying to type.)
So, yeah.  Work today, readings on the train, assignment tonight.  I'm just typing this up as I eat my breakfast. *g*
