I don't have a wedge pillow, but I do have an artfully constructed pillow mountain. I make the bed around it and it looks really silly, and poor DH is afraid to touch it lest he incur my wrath. And it does help, a lot. It's got me this far without using meds.

I had heartburn from avocado on toast this morning, so bland foods aren't even doing the trick. I was very refluxy as a kid, a real Spewy Louie, so it's not really surprising.

I've gone for Gaviscon, and will see how it goes. Haven't found any fruit tingles yet though - will try the servo in the afternoon.

Thanks for all your replies!
