Sounds like it's working just fine. However, H, would be better at confirming that. Nonetheless, what ozone unit are you using? Meaning, what company and are you using pure oxygen or a concentrator? In you other thread you mentioned ozone and cholesterol does it help lower cholesterol as well? I'm 100% certain I need to lower my cholesterol and possibly have a blocked artery. I don't have insurance, but am having chest pain, along with stomach issues. At times I feeling like going to the ER, but then I calm down and talk myself out of it. No matter how bad I feel. I have gone to the Doctors in the past and no help, so I feel I need to take my health into my own hands. I am as H as suggested taking lecithin granules, I stopped drinking and tobacco, along with D.E. in my water. I don't know if these things will help someone who alread has blocked artery....
