windwalker…… I feel like I can only get about 20% of air when I breathe. I took oxygen level with the clip on finger type tester and it was 85%. Can't do too much at that time. It rather scares me to go on with it. So, now they have me on 2 weeks on -- 2 weeks off. I'm on again right now. I've never had any coughing relief but have been unable to do the 28 day program. I've done it on a lesser scale for over a year now. I'm going to inquire about adding the second product to it. Thank you
