Crab nite dinner at friends house

Had crab last nite at my friends place and eventually had a crazy nite, we all got drunk and finish up 5 x bottles of "flower diu", 1 x bottle of white wine and half a bottle of Vodka. Hahahhaa, i thought i will have a sick leave today but eventually i managed to get up for work and even had coffee with my friend before work.  Although my head is now spinning and i think i have a hard time keeping my eyes open and my mind clear I still pretend im ok in front of my collegues.
