Also once per week I allow myself an espresso, and I get a nice buzz from it that lasts the entire day.
I wouldn’t claim it works the same way for everyone, but the difference between coffee being a treatment for migraines and migraines being a symptom of coffee withdrawal may be indistinguishable in immediate term.
I quit caffeine for about 2 years and the headaches never subsided (except the caffeine withdrawal ones of course).
They are just a fact of my life I’m afraid.
As much as I’d like to get off of caffeine I am very grateful to have is as a remedy.
And it’s pretty important to realize that well-made decaf doesn’t have to taste worse than regular coffee. James Hoffmanns decaf project proved this for me, and his video about decaf sold me on the idea: decaf drinkers are the OG coffee drinker, drinking it purely for the taste, even without the drug-induced high that caffeine gives you.
