I had a voicemail from the Dr's office when I came home Wednesday night so I called them after I got to work Thursday morning. Insurance actually approved the PA! I was shocked that they did this and didn't require any further proof (i.e. the esophageal pH test) that I have GERD to continue covering Dexilant.
I'm hoping to eventually not need medicine on a daily basis. Everyone says losing weight helps, 25+ lbs. I lost 20 lbs last year and it obviously didn't do anything for my GERD symptoms. Hopefully the weight I lose on Weight Watchers will do the trick. I'm also going to look into taking aloe and/or papaya juice and digestive enzymes.
