Thank you for the comments, Sue! You are right that the table salt I use does show some content other than NaCl. However, I was a bit desperate since I am still waiting for the 7% saline order from Amazon, but the vendor isn't taking my payment nor deliver, so I may just keep waiting. I also ordered Reduced L-Gluthione after reading on this forum, and will give it a try once I have the 7% saline solution. Re thick mucus, I am taking NAC (600mg x3) daily. In addition to NAC, other supplements I take are: Vitamin C, Fish Oil, Selenium, Vitamin D, Vitamin A, B12, melatonin +Mg for my sleep. Are there other supplements you recommend MAC patients take? Thanks!
