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.
I’m late to this. But it sounds like you are really dependent on caffeine. In which case quitting caffeine might not be an option. However the underlying issue, the main reason why you need caffeine, is what I believe you should take a look at. Is it the lack of sleep? Performance anxiety? Could it be add/adhd?
