Good luck! I'm glad to hear that you are starting to respond to changes in diet. That is, of course, the first step (and sometimes the hardest!). Since you're just beginning the non-invasive treatment of GERD, it will be a while before you have a definitive answer as to whether or not that will do the trick.
Of course we will be here to support you along the way! I'm sure your wife has gone through a lot with her surgery and adjustments afterward. Glad she sent you to us!
Good luck to both of you.
Here's hoping you are well and ready for your mountain bike adventures!
