SKI first, try to love the boots GOD they hurt on the first day (you need the apres ski to get through the pain!!!! pain killers or drink?)
try the spas, they help (austria has loads of them)
then the pub
by the time you have done that (and drank in the traditional Austrian way) you wake up and do it all again a bit worse for ware, but skiing will get rid of the hang over (try not to break anything whilst getting sober)
then start again!
