Only option for me at my workplace is either coffee (undrinkably bitter) or expired tea (tastes like rot). Did not have enough time yesterday to make myself tea for the next day and the shop where I buy energy drinks is closed. I extremely drownsy and my head hurts.
EDIT: Coffee is undrinkable to me, quality or not. The bitterness will just overpower everything.
Some over the counter painkiller to get rid of the headache if you can.
Just take a shot of the coffee in the morning to avoid the headache. I don’t know how bitter it has to be for you to prefer a headache over it.
