This is good advice, I had similar issues with acid reflux. Though I didn't have the patience to cut so much out of my diet. I ended up starting a diet journal and tracking closer attention to what food & drink triggered my acid reflux. Coffee turned out to be the worst culprit, and cutting out coffee eliminated 80% of my acid reflux incidents. It's probably best to go the full diet change route & slowly introduce new foods again, but if you read the OP's recommendations and think "I can't do that" there are other ways.
