@rammbo . Douglas, you should consider trying WEI lab herbs. They are a little less than what you are paying but you can try a 2 week supply to see if they begin to work for you. Several on this site have improved and a couple have gotten off oxygen. I was stabilized over 4 years ago and my tests have been steady and consistent ever since actually improving after I took the herbs. There are a lot of stories where people quit their oxygen and had major improvements. Their herbs also got rid of my GERD for quite a while. Call Frankie at (612) 808-8785.
