I would binge drink water during class. It was the most relaxation you'll get. The room feels really cold when you first walk in because its like 100 degrees out there and 85 in the classroom. Then after 300 some people are sitting packed in shoulder to shoulder in the little auditorium, it starts to get really hot. But its as cool as you're gonna get. But then again that was summer. It should be a little more managable during the fall.
and they will prescribe water for everything down there. At OCS, theres nothing that cannot be fixed with water, motrin, white tape, ice, and stretching.
