I learned a lesson lastnight: Free alchohol is very bad

I'm in Austin at the South By Southwest Interactive Festival.  By day I'm telling people about the Microsoft web stack and Silverlight.  But anyone who knows anything about South by Southwest, they know that it is notorious for it's nightlife as well.  Lastnight I attended two parties.  The first was thrown by Microsoft and the Phizz Pop team.  Naturally I had to go to that one.  I also attended the Server Beach/ Rain City party.  Free drinks all night from 7 pm until 2 am with only a slice of Pizza in between.  Not good!!!  I should know better :-).
