I won several days of contemplating what I would do with a giant mountain of dollars. It was worth the price.
My wife and I did the same thing. In the end we decided we really wouldn't change our lifestyle much aside from not having to work anymore. We'd just put the money in interest bearing accounts and live off the interest. And then of course our kids would be able to do the same once we die.
Basically, we'd just become a family of lazy unproductive citizens living off of unearned wealth and not really giving anything back to society.
