I'd like to thank Pillhead at Jezebel for this insight from their latest post Counting Sheep is for Suckers:
"I didn't ask my doctor for a sleep aid, he just offered me an Ambien prescription and I said, "Why not?" That night, I popped half and climbed into bed with a book. The next morning I woke up with the light still on and my head on the book -- I hadn't even made it through one page before sweet, sweet Ambien knocked me out. (This is why I have a theory that the decline in literacy rates and the rise of sleep aids are inextricably linked.)"
Sweet Ambien indeed... and, you don't get those pesky hangovers that come with drinking a bottle of vodka before bed.
