Alistair's Energizing Elixer

You create a magical elixir capable of rejuvenating the body and mind. The spell turns the coffee mentioned in the components section into a fizzy liquid of a color you decide. The liquid is also flavored how you decide. Upon drinking all the liquid in the cup you gain the ability to stay awake all night, and still gain the benefits of a long rest. To gain these benefits you can only engage in light activity such as keeping watch, reading a book, or transcribing a spell. The spell however does not remove exhaustion if you had any before drinking the elixer.
