Thanks again for your report. I was alarmed to see you on oxygen. Since it can’t hurt, take a good quality vitamin C tablet morning, noon, and night with water and after food. In a couple of weeks, I expect your lungs would heal enough to let you get by without the Oxygen supply. Remember, ALL our body’s cells get replaced on a regular basis. Some in our eyes get replaced in a day or two. The bones in 5-6 months. Dr. Tennant of Texas says ALL chronic disease is due to inadequate cell replacement. The Vitamin C complex is necessary for adequate cell replacement which you have and are not getting. Your next stage is the grave unless you improve your nutrition so your body can make cells.
