Usually, I avoid caffeine, tea, nicotine for health reasons, to avoid gastric reflux.
I've spoke with some International Society of Krishna consciousness - they also avoid mild mind alterning substances.
Coffee gives me problematic stomache motility. So is nicotine. So I've been avoiding mmost of my life.
However, recently learned about different beans, oriental, acidic, bitter non-acidic. And espresso made from later seem worked good. Because espresso extracts only all safe, good alkaloids, taste, flavours, aroma in first 60 seconds. And avoid long-extracted irritating terponoids, tannins.
I lease cuprum turka that I bought as a gift to fellow coffee enjoyer. He prefers it to italian coffee machine.
Also somehow zero sugar coca-cola does better in my digestive tract than coffee. idk about pepsi. Does anyone on denpa-chan seriously prefer pepsi to (over) cola ?

Cold brew green tea is dope as bottled nestle.
