Sleeping disorder. Symptoms include drowsiness, instability to stay alert, and sudden sleep. Symptoms manifest themselves only when driving/riding in a automobile.
I hate going onroad trips with Anthony! Thirty minutes in and he's asleep, leaving to fend for myself the next 4 hours, that dude must have a case of carcolepsy.
A nonthreatening condition found most frequently in children of all ages and a small percentage of the senior citizen population.
Victims of Carcolepsy typically show symptoms such as falling asleep as soon as a car begins to move, waking up hungry and complaining of a sore neck for hours.
Dad: "Gee whiz! Is he asleep already?"
Mom: "Oh, yeah. He's got that Carcolepsy.
I tend to be Carcoleptic, so I bring a pillow with me on road trips.
