I decided to quit coffee about a month ago because even though it is not that harmful to my health I realised I only consumed it because of addiction rather than it making my life any better. Considering I abstain from all other social drugs anyway, and it was also the last big source of sugar in my life, that was also convenient.
The constant headache went by in a week or so, but these last two days have been the first time since that I haven’t had sudden urges to nap in the afternoon. I never expected quitting coffee to be so disruptive for such a mild drug, so I can’t even imagine how much worse it would be with alcohol, opioids or crack or doing it while particularly busy. It also helped me get my sleep in order, which I dumbly didn’t even think about beforehand. Heartly recommend trying it out (in your time off!).
Me too, 4 months ago. First time with success. Substituted coffee with black/green tea. I feel great, no headache, etc…
