Dr. Jan Adams, the non-board certified plastic surgeon who operated on Kanye West's mother the day before she died, has been sentenced to one year in jail after rolling over to a charge he drove super drunk last year.

Adams pleaded no contest to one misdemeanor count of DUI over an incident in the Bay Area last June where he was caught driving the wrong way on a freeway with a *lo** alcohol level of .20 -- more than twice the legal limit.

Adams will receive eight days credit toward his sentence from the time he served right after he was arrested.
