Is Ambien the Culprit?

So some dude from Stratford showed up to his dental appointment 5 days late, and naked. When police tracked him down at home he claimed to have been sleeping all day.

I tend to believe the guy. With all the weird stories about things people do while sleepwalking thanks to Ambien and other medications for insomnia, I don’t see why this guy couldn’t have been a nude sleepwalker concerned about his dental hygiene.
