Drank only black coffee for years until heartburn started to catch up to me. I found milk in general helps with that, so now milk goes in all my coffee / tea and it's really quite nice.
You want milk go succle a teet, coffee should be consumed on its own. Brewed Coffee, Americano, or Espresso are the only acceptable ways to drink coffee. Same thing with black tea, English Breakfast tea tastes just fine without milk or sugar.
