Happy 21st! Go and get your free drink; you deserve it! It will get better, honest it will - the first few days back to the semester are always the most stressful (especially spring because you don't have the extra 'move-in' time or the excitment of catching up with people after a whole summer). As for the wrist, if you can deal with noise while sleeping maybe try music or a book on tape so that you have something to think about other than how your body is positioned. Just the break in thinking about it may give you time to drop off.
