Some Twitterers may not have been aware that Musk's tweet was a reflection of his words during Tuesday's Tesla annual shareholder conference.
The only transcript I could find has him talking about movies and then saying: "So yes, I hang out with my kids, see friends, normal stuff. Sometimes go crazy on Twitter. And it sort of little red wine, vintage record player, some ambience, magic, magic happens."
Could it be that he really said "Ambien"? Some agree that he did. Tesla didn't immediately respond to a request for comment.
This isn't the first time, however, that Musk has made a Twittered reference to Ambien use. Last year, he replied this way, after being asked whether he writes his own tweets: "I'm the only author, so, love or hate it, that's me. I've learned some lessons though, such as tweeting on Ambien isn't wise."
