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.
Taper out, your body and brain will get used it it in about a week or two. If you’re like me life will stop having meaning as a side-effect. My longest time away from coffee was 3 months, and my mind did totally not get used to it in that time.
I have no doubt about coffee being a pretty hard (even if benevolent) drug.
