In reply to the salty taste, I think it's part due to a more bland diet and maybe due to some dehydration. I have experienced to the same thing. It's not as bad now as I am 1 year out but it was definitely there. As for the air in the esophagus, I still get gurgling while I eat. I dont know if it's because my stomach is more of a tube than a pouch. I cant control it but it doesn't stop me from eating. Sometimes it happens after I eat too. It's not like a burp, it's just lose air that comes up.
