Where to find PulmoSal 7%?

First post here. I've been a stealth observer for awhile, and now it's time to actively participate. Baby steps....

I've been looking for PulmoSal hypertonic saline 7% for awhile now. I would like to see if its buffered pH helps me. When I switched from nebulizing every other day to every day, wow, my LPR hit the roof. I suffered through the transition, and went through acid-food detox.

I'm wondering if inhaling that generic low pH saline is causing pepsin to destroy my lungs. Hence, I really want to try the higher pH stuff. None of the pharmacies I've contacted (and I've contacted a bunch) can find PulmoSal. The manufacturer hasn't returned my emails or phone messages. Please tell me where you get it.

Thanks!
