well, idk about your team (you sound like you play), but the major issue with our team is getting everyone out of the clubs the night before a game. seriously, during trainigs, we are always like "yeah, saturday is gameday, no drinking on friday, you can still get hammered after the game,etc" and we always end up with at least one third of the team being very unreliable.
normally i dont drink too much and not too much before a game, but this other time, there was a outdoor party going on at a lake (around a good half hour walk away from the town up in the mountains) and yeah, i guess it was the only party ever going on up there (/sarcasm) so i couldnt let it go and walked home with a buddy (the others just ordered a taxi, pfff, uncool) in total darkness at like 5 a.m.. i live directly where the road up the hill leads into the town, so we made a nice omelett at my place and he slept on my couch. departure for the tournament was 8 a.m.. the worst thing was probably that we were kinda the fittest dudes on the team.
