SNICKERS - I eat them during exams. Law school exams SUCK. several hours long, essays. My three exams this semester are all 4 hour exams. And I'm writing for most of that. Snickers are great for keeping my energy up. I just laugh at those commercials that say "not going anywhere for awhile?" because I picture myself trapped in the exam rooms!
DOTS - DOTS - DOTS - DOTS - DOTS - DOTS - DOTS!

I LOOOOOOVE these. Even though they get stuck in my teeth a little bit. One of the attorneys I worked for a couple years ago liked them too, and we got everyone in the office addicted. People would buy them and then sneak in each other's offices and steal from each other's boxes, it was nuts. One paralegal used to tape up her box with some serious tape if she didn't finish it all at once. The attorney went to her desk with scissors and cut the whole box in half!

He didn't take any, just left the mutilated box on her desk. She got revenge though - she took the leftover dots and lined them up along a shelf in his office behind his head. He had a client in there later that afternoon and he asked why he had gumdrops on his shelf like that.
#1 fave - Lindt chocolate bars, pretty much any flavor (hazelnut is nice

). They're Swiss chocolate that I got hooked on when I studied in Germany. Much to my delight, I discovered that they're not too hard to find here.
