I have had those problems for nearly 20 years with heart burn and acid reflux. When it first started the doctors assumed it was from the medications I was on, but it continued even when I went without meds for a few years. It seems to get worse during flares when the AS is active and there are a few drugs that increase it. I love a good banana sandwich from time to time but they don't like me.

I have found the reflux is not as bad if I avoid eating anything after 6:30 to 7:00pm. Some foods like onions and a few spices I won't eat after 5:00pm and I don't end up waking up all night feeling like there is a fire brewing.
