I did buy Heartburn No More when my GERD first kicked off last year. In brief, it is instructions on how to follow a naturopathic diet, combined with some advice on how to heal your LES. So on top of the diet he advocates using honey, not eating any food which is sharp or rough, and I think one other agent which I forget (but I can dig it out if you like). The diet is very similar to other naturopathic diets which you can read for free on the Internet - along the lines of no processed food, no fatty food, no stimulants, low carb, no sugar, lots of veg - you know the kind of thing.
The book offers a three day symptom relief thing, which I did try to do some of, but the honey made no difference and I just felt miserable at the thought of further dietary restrictions.
I would say that these type of "cures" work great for people who have had a poor diet, lots of fatty food, fast food, alcohol and coffee - but for those of us who have already tidied up our diets, I don't think you're going to see any great changes. If I was going to try any new diet I would try the low pH one, but with two small kids and the existing dietary restrictions I already have, I just can't face it :-(
Hope that helps,
