What are some of the shittest experiences you've had in the Army?

Story time:

I've been hitting up old friends because I'm leaving for basic soon. Some of my buddies are in the military, the majority of whom hate it. I spent Saturday night awkwardly watching my Sailor buddy have a drunken existential crisis while bemoaning the fact he didn't go to college.

There seems to be a sort of trend with my friends who enlisted: 1. Those who joined out of high school and expected it to be high-speed awesomeness and 2. Those who worked/went to college for a year or two, became reasonably jaded, and had no expectations about the glorious military lifestyle. The latter seems much more content than the former. I intend to fall under the latter. I can't imagine Army aviation is too much worse than AmeriCorps.

So what's some of the bullshit I can expect to encounter on a daily basis?
