Yes cutting out gassy, acidic and fatty foods can help, as can trying a dairy elimination diet for 2 weeks as a lot of refluxers also have a dairy intollerance.
I found the 1 thing to avoid for me and Z was orange juice. You could try apple or cranberry juice as a substitute?
That all said, you don't want to deprive yourself either too much so do what is achievable for a few weeks, then review. If you do dairy elimination you do have to do all dairy though for a good 2 weeks.
