I had hardly any during my test yesterday which is so unlikely I can't believe it. I usually can lie flat for more than 15 min. but slept flat all night, no problem. And no acid aspiration, burning or throat or chest tightness.
Is it possible that the mamometry test before, or the pH test itself does something that reduces reflux. Maybe the electricity tightens the valves temporarily?
Of course, now that the probe is out, the reflux is acting up off and on all day.
