Phase 1 - Wake up in horrible, soul-crushing suffering.
Phase 2 - Try and force the pain (and the rest of the alcohol) out of you through sheer force of will.
Phase 3 - Take deep breaths, tell yourself that this too shall pass.
Phase 4 - Realize that Phases 2 and 3 were useless, thrash around in suffering and regret your life choices, swear to do better to yourself next time.
Phase 5 - Eventually feel better, go out and do make the exact same mistakes again.
