Hi I'm Dee. I had my surgery on 03/05/2013 and have had similar results. I am also using Premier from Costco and I love it. Do you get the sensation when drinking your water or tea that it is bubbling back up into your esophagus? It's like acid reflux but almost feels like little air bubbles. It's really uncomfortable. The Dr. Told me it's from swelling but I was just curious if you had experienced the same thing? Best wishes. Dee
