A man is sitting in the coach section of a flight from New
York to Chicago biting his finger nails and sweating profusely.
Noticing his disturbed expression, a flight attendant walks
over and says, "Sir, can I get you something from the bar to
calm you down?"

The man gives a nod of approval while shaking terribly. She
comes back with a drink and he downs it quickly. Ten minutes
later, the flight attendant sees the same man shaking and
biting his nails. She brings him another drink which he
swallows immediately.

A half hour later she returns to see that the man is shaking
uncontrollably, and apparently crying. "My goodness," the
flight attendant says, "I've never seen someone so afraid to
fly."

"I'm not afraid of flying," says the man sobbing loudly, "I'm
trying to give up drinking."
