There's quite a long review for heartburn no more here
helpingheartburn.com/heartburn-no-more-review-work/ which might help.
I think it is based more on diet as well as some tips and supplements. Change of diet and then giving the gut and body time to heal sorted my severe reflux out so I hope you all make progress. Stress was also a big factor for me I think, looking back, although at the time I didn't realised I was stressed and depressed.
