Hi there,
From my experience, the best things that you can get to make your life easier are the following:
For clinical, get a cheap watch with a seconds hand that you won't mind tossing if it breaks. If you are taking 6am clinicals, it is imperative that you eat in the am, as you will be starving and needing to pee bad by 10am. I have found that plain white athletic tennies do me just fine, but I have heard those special nursing shoes are pretty nice too.
Also, don't waste money on those pocket size reference books. You need a 2005 Drug reference guide, the one that's about 6''X10". You will use it constantly and students were always taking mine.
For lecture, I would recommend getting a pack of green highlighters, and lots of index cards. Also I have found that taping the lectures comes in very handy, although I always thought it was a bit dorky before now!
Finally, get yourself a bottle of advil, because you will need it!
Good Luck and congrats!
