• Ambien is one of the top 20 drugs found in the blood of drivers pulled over by Wisconsin police, says Laura Liddicoat, a supervisor of the forensic toxicology program at the Wisconsin State Laboratory of Hygiene, who presented her findings at a February meeting of the American Academy of Forensic Scientists. Ambien showed up in 187 drivers arrested by Wisconsin police from 1999 to 2004, according to a separate analysis by the state lab.

• Ambien was linked to 99 traffic accidents reported to the Food and Drug Administration between 1998 and 2005, according to an analysis performed this month by Charles Bennett, a professor at Northwestern University's Feinberg School of Medicine. Bennett notes that the total number of Ambien-related car accidents could be much higher, because, on average, only about 1% of drug problems are ever reported.

• Nineteen patients were eating in their sleep after taking Ambien, according to a June 2005 article in the journal Sleep. One found a near-empty tub of margarine on her kitchen counter, with no idea who had devoured it overnight. Two started small fires while trying to cook.

And yes, Colin Powell, John McCain, Brian Williams and many other high-level politicos and professionals take Ambien. Doesn't everyone?
