So far so good, although it's only been a day or so, so I can't really judge it yet. Especially as I spent most of it vegging out in front of the telly :)
After drinking vast quantities of random cocktails, I managed to avoid having a hangover. Only casuality is a missing glove...but I think that just fell out at the party rather than on the way home. And for reference to those that were still at the party when I left, the shortcut isn't (a shortcut).
