I used to use Ranitidine for acid reflux. Found that it becomes less effective over time, and the better long term fix (for me) was to cut out the fat, cut out the alcohol (or reduce it)
Plus keep a packet of Rennies in the flight back.
AME was not bothered in my case, unless the acid pain became debilitating. The diet adjustment means I rarely even take a Rennie these days.
