The day after
For the hung over, your phone is your friend. iPhone users can download Hangover Cures (59p) to hunt for the elusive remedy, as well as Easy Excuses (free) or Simple Excuses (59p) to get out of whatever meeting you foolishly planned. If you have a tendency to take a taxi home and forget the exact location of your vehicle the next day, a car-finding app will make your life a lot easier. Try Car Finder (59p) for the iPhone, Car Locator ($3.99) for Android, Car Finder (free) for BlackBerry, or FindMYcar ($2.99) for Palm. And, of course, if you discover any incriminating or outrageous St Patrick's Day texts, turn to the Texts From Last Night (59p) app to record them on the net for posterity. Only 364 more days to go until early-morning drinking in a leprechaun outfit is considered socially acceptable again.
