During my museum career i would get a couple triple machiato’s at the first espresso cart in Portland(circa 1982-95…that took its toll on me . Hiatal hernia like awful heartburn. I gave up coffee for a few years. My career was stressful but loved it. The caffeine was my go to. Long hours. So for a few years i replaced coffee with postum and Caffix both grain beverages. Then over time I brought back coffee and it was okay.
