For me, it wasn't the coffee it was the caffeine. Switched to decaf and my acid reflex disappeared nearly instantly. Try slowly swapping out 1 cup of regular for decaf, followed by another, followed by another, until you are off of regular coffee entirely. Over a surprisingly short-ish time, that "I feel sleepy without coffee" thing will go away and if you're in the same boat as me, your reflux will disappear too.
