Yes absolutely and all my docs have confirmed that there is a close connection between GERD and breathing issues and vice versa, because the two structures are so close together (apparently). I started taking Zantac or Pepcid to address asthma-like issues and it helped. And when my sensitive lungs are exposed to, say, a new carpet or oil paint, I also get GI symptoms, so it works both ways. Oddly simethicone (Gas-X) helps both my breathing and heart.

Try treating Gerd with Pepcid, stop eating after 5 or 6pm, and see if your breathing gets better. It helped me and I hope it helps you.
