How about involuntary DUIer's?
I took the sleeping aid Lunesta (Ambien(eszopiclone)), I remember just about to hit the pillow and "came to" in a police station for DUI. Not only that, but I sideswiped one parked car and destroyed another within 500 feet of my place, with no memory of it.
The report claimed my pants unzipped, belt unbuckled and generally unkeep, hell I was lucky to of been dressed at all. I blew a 0 three times on a breathalyser which takes 45 minutes to recalibrate after each test (I have to take their word for any of that); it was the blood test that took me down, apparently I Ok'd it; a breathalyser is all I'm required by law and I knew that.
I had an ignition interlock installed that I had to blow into before the car would start, it was nothing but problems, from it's aluminum wire interface to the copper of the cars main power line to getting the blow down, I've sat many times trying to get the interlock to accept the "blow".
When I had it removed (a year later) they acted like it was the first time one was ever removed, it took my new drivers license as proof and even then they weren't that sure. As soon as I drove home I checked the splice and sure enough a 28 gauge wire was used to join a 10 gauge wire, and by it's connections I figure this persons first electrical experience.
$100 a month it cost to drive down and have the interlock read. Now they've gone to "ankle bracelets" that monitor a person 24/7 at $100 a week to be read.
I post this in my attempt to warn others of the side effect of "sleep walking" when taking Ambien/Lunesta or the like, If I hadn't driven (and where to?) I might of never known. I'll never take it again and do advise others to avoid them.
