In the category of things that would make me shake if I couldn’t have it:

1. Caffeine - Coffee (black), green tea, or yerba mate being the preferred delivery method
2. Internet
3. Camera
4. iPod
5. The love of a good woman (the woman, in this case, being my wife)

And in the category of things that might cause me to whine a little if I were to be without them, but on the whole I would be able to function in their absence:

1. Advil
2. My Sigg Water Bottle
3. Moleskine Squared Reporter Notebook
4. Mechanical Pencils, preferrably with a .07 lead
5. Chocolate
