EuphoricI took a poorly postured nap in what civvies' would call "The Barracks" and anyway, I woke in horrible pain from the posture, then I stretch and my back and neck all POP! like 50 likes more, more times than I have vertebra but w/e, and it was that deep, CLUNK popping, loud enough that a another soldier heard it.
Holy shit that felt my good, better than anything in my life.
