Currently doing an Insomniac's Gambit. For those of you who don't know, this is when you mess up your sleep schedule badly enough that you attempt to fix it by skipping an entire night of sleep then going to bed at a reasonable hour the next day. Crucially, it does not work
"yeah dude I'm gonna sleep in 20 minutes" -- the most "will stay up another 4 hours" guy you've ever met
Okay but get this -- they'll *never* expect the rare Double Insomniac's Gambit
