I'm not sure if your issue will be the same as mine but I suffered with GERD symptoms for roughly 2 years. Spent so much time trying to figure out what to do or how to prevent it with no luck. I eventually found out that I can't eat gluten. Once I cut gluten from my diet all the GERD symptoms went away. Just thought I'd throw this out there in case it helps. If you haven't already, try cutting gluten for a week and see how you feel. If that doesn't help then I hope the pillow helps!
