Patient tells his doctor: "It is very hard for me to fall sleep."
The doctor replies, "Try counting up to 2000. Come back
again after a few days."
The next time, the patient says, "Doctor, I did what you
told me to do but I still can't sleep. I was able to count to
1000 but
I was so sleepy I had to get up and have a cup of coffee to be
able to count to 2000!"
