I'd probably go too some remote island resort for a week first to think about what to do next and get over the initial shock then probably extend the holiday for another couple of weeks and get friends there and destroy my liver slightly then head back to reality and begin the daunting process of seeing people right, then get myself sorted with house, car, boat etc.
Then live off the interest while traveling around the world on the cheap for a year... then who knows, oh and I'd retire... no need to work anymore (I'm a creature of comfort)
