Waking Up Is Like Being Drunk

Via CNN:

If it takes a while to clear the cobwebs after waking up, that's understandable -- "sleep inertia" leaves some people so groggy they might as well be drunk, researchers said on Tuesday.

"For a short period, at least, the effects of sleep inertia may be as bad as or worse than being legally drunk," said researcher Kenneth Wright of the University of Colorado at Boulder.

That befuddled feeling usually lasts for at least a few minutes but may be detectable for up to two hours, Wright wrote in a report published in this week's issue of the Journal of the American Medical Association.
