University tramp comps here are pretty much designed to have drunk competitors.... Usually synchro on Saturday afternoon (hopefully sober), then the social, usually including drinking games on Saturday night, with the individual competition from some ungodly hour on Sunday morning. Last year someone wrote on a Facebook group for one of them after the timetable was released 'can we please not have elites on at 9am, it's not safe!' I laughed, until I realised that it meant that MY category would be on at 9!
Personally I've never competed drunk but I HAVE competed severely hungover it totally does help with the nerves! (The only thing on my mind was getting through ten skills without vomiting. Took the pressure off a little bit!) and I won...
