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.

I don't suffer GI issues because of coffee consumption, but I do have GI issues that I'm currently resolving with Visbiome.

It's expensive, but it's really the only probiotic that has ever made a difference for me.

My acid reflux is almost completely gone because of it.

I have GERD and take esomeprazole daily. I used to take omeprazole but it gave me headaches
