A good laugh and a long sleep are

A good laugh and a long sleep are the best cures in the doctor's book.
- Irish Proverb

"At that point I ought to have gone away, but a strange sensation rose up in me, a sort of defiance of fate, a desire to challenge it, to put out my tongue at it. I laid down the largest stake allowe-four thousand gulden-and lost it. Then, getting hot, I pulled out all I had left, staked it on the same number, and lost again, after which I walked away from the table as though I were stunned. I could not even grasp what had happened to me." - Fyodor Dostoevsky, The Gambler
