For coffee, I've seen people recommend putting in a dash of baking soda in the drink to reduce the acidity though I haven't tried this. I also tried some of the low-acid coffees and they were fine though the flavor is in no way comparable to my favorite poison :). Drinking these beverages when you are not expecting to recline (e.g. in the morning and early afternoon) may also help.
However, if you feel these symptoms are pretty bad, it is worth going to a gastroenterologist - chronic upper GI acidity can lead to GERD and that can lead to esophageal cancer.
Could you talk more about what your acid reflux was like? I'm curious about finding new ways to treat my own. Been on 20-40mg of (es)omeprazole daily for a decade.
