I used to pop Pepcid AC's like candy. Having nothing to do with my reflux I started doing IF with a low carb diet, and about a month in I realized I hadn't popped a single Pepcid. It's been over a year and I've had like 2 or 3 of them, when combinations of foods just provoke the reflux.
I can't say for sure, but I think both were important factors for me.
Btw, the IF I do is called 4:3, I think. Basically, 3 24-hr fasts a week. The rest of the days are regular. That's it. I don't really hold to it strictly anymore. I didn't do any full 24-hr periods in the last week, but it definitely trained me to eat a lot less, and that's what really helped the reflux.
Just passing this on, in case it helps you.
