jack-a-leg
When you feel like a total wreck because of jet lag. It's like being hit by a truck and then having your brain scrambled.
I got off the plane and felt like a jack-a-leg, I couldn't even walk straight.
My sister got a jack-a-leg after the flight, she cried in the middle of a restaurant.
I was so tired from the jet lag, I looked like a jack-a-leg and fell asleep on the couch.
