Coffee has been a "side hobby" of mine for years. Different beans, grinders, you name it.
But now that I am older I can see how bad it is for me. My sweat smells different (as if I haven't showered in days), my jitters are increasing, I get very unfocused and aggitated and worst of all, mild panic attacks.
I spent few years thinking that something was really wrong with me until I noticed that coffee has a huge negative effect when I am on crunch time.
I started with teas, still not a fan, and decreasing coffee. Also moving to decaf, where are hard to enjoy because of taste.
Not sure if anyone is on the same boat.
