Water. After juice, tea and a sly can of Coke.
All the better for not drinking any booze, not having knocked anything over, not having started any fights, not having said hurtful things, not having shouted at strangers, not having woken to the shakes and sweats, not getting over sentimental, not succumbing to self-destructive impulses, genetics and personal weakness and not killing myself by a slow, unglamorous and downright pissy route.
Good luck with the taper. Just watch the other.
