Get some rest and recovery, Blueberry. I hope you win your fight with TSA. One of my friend's sons is starting his 3d year of med school, so i have some idea of the stress you are under. He just finished his surgery rotation, where he had to be in the OR for 6 hours and couldn't leave to pee. This necessitated restricting water intake, which is not exactly good medical practice when it is 95 degrees out.
