No, it is also for a great deal of enjoyment.
I used to drink at least 2 cups of coffee a day, and at least 3-4 of black tea.
over a year I slowly backed down to just a single coffee coffee in the morning.. then eventually switched to decafe coffee for that one. I had headaches for about a week, and I think I was irritable.
Recently I stopped even the decafe coffee, and now drink 1 or 2 decafe tea a day when it's cold.
I feel great, save money and don't miss the ups and downs of real coffee - I used to get the sweats, shakes, funny shallow breathing, etc. etc.
I also had no idea I was living life through a "fog", that I didn't even know about until a few months after I stopped. Life is much better now.
Then itβs magically gone.
Not even close to a full week.
Just do it.
I quit caffeine a few years ago. I'm not an unusual mutant. I have the genes on markers rs4410790 and rs2470893 that indicate a typical reaction to caffeine. (https://enki.org/2017/08/13/quitting-caffeine/)
Most people experience a temporary increase in productivity until they build up a tolerance for caffeine. Thereafter, they are just paying and consuming to avoid headaches and reach the baseline.
