Insomnia
A man went to the doctor complaining of insomnia. The doctor gave him a thorough examination but found absolutely nothing physically wrong with him.
"Listen,” the doctor said, “if you ever expect to cure your insomnia, you just have to stop taking your troubles to bed with you."
"I know," said the man, "but I can't. My wife refuses to sleep alone."
