Redditor and Ambien user ajscraw claims to have woken up to this note, written the previous night in the middle of what appears to have been a full-on, Fear and Loathing in Las Vagas-level drug trip. It may not be very helpful in letting him know who, if anyone, actually stopped by, but it is very helpful letting him know he should cancel his Ambien prescription immediately. Or double it, depending on how much he values having a grip on reality.
