I'm 34 now, and I've tried to quit coffee several times with mixed results. But I could only last 2-3 month at most.
I was fed up with reaching a point where I wasn't getting any extra energy, and at most my hands would start shaking. And overall with my ADHD it just made it harder for me to focus.
I'd tried switching to mushroom coffee before, and I liked the effect, but I can't stand the mushroom aftertaste, so I was looking for something else.
And now after a few weeks of switching to mushroom protein coffee and reducing my caffeine intake, I'm incredibly happy that I didn't have to give up that morning ritual and feel better without any aftertaste.
I'm also looking into switching to non-stick pans so I don't have to use oil if it's possible, because I'm constantly exceeding my daily fat intake limit
