Potion of Sleep

You’ve got troubles, I’ve got troubles, we’ve all got troubles.
Tell me your troubles, and I’ll make you a potion for them.
Got a cut? Got a scrape?
Pour this on it.
Losing your hair?
Rub a little of this one on your head. (And be sure to wear gloves. Trust me on this.)
Love? Pain? Joy?
This one’s special: sleep and death.
Just depends how much you take.
Careful, kid.
I got ’em all in these bottles, every color, every flavor.
Sip this, rub that, some drops in your eyes.
Give me your arm, this won’t hurt a bit.
