When you wake up from an insane night of partying at some sort of Dubstep rave and your neck,arms and any other body parts are stiff. you also have an insane hangover and the dubstep could have influenced you to do things that you wouldnt usually do (dubslut).
Either liquid niquil or any liquid drink with melatonin, Ashwaganda or other sleeping aids in a liquid form. If warm tea helps you get to sleep that could be sleepy juice too.
I could not sleep so I chugged some sleepy juice and now I'm so tired and sleepy.
