One month of relative bliss thenn

after a weekend away from my home, my Acid Reflux or GERD came back with a vengence. It's as if the Nexium did nothing. Was it the food? Possible, but I kept a decent eye on what I ate, was it the overly soft bed? again possbible, I woke up with the familiar feeling in my throat.... but that was 3 days ago, and it's only gotten worse.

Am I becoming Immune to the Nexium? It's again a possibility. I could rotate through the GERD medictations. I'll go back to watching what I eat like a hawk, but please, Heavenly Lord above, maker of all that is seen and unseen, I don't want surgery.
