Sounds like you are on it!
It sounds like you might find the links below of interest. Using information I gained by reading Klenner’s work with high Vitamin C, referenced in Cathcart’s link, I may have saved a woman’s life.
Dr. Cathcart (see first link) has treated 9,000 patients with high C doses over 10 years. For a person with some medical knowledge, this link has useable details on how to treat at home with high Vitamin C doses, if hospital is not available. I have also found that when I used or gave to family high doses with fever, the fever would always drop 2 degrees in a half hour. Vitamin D has also been found helpful. I now take 2000 to 5000 IU of D depending on the season. This is in addition to the 3 to 6 grams of C I take daily for my allergies. You can also demand that the hospital treat you or your loved one with the intravenous form of C, and have your lawyer on call if they object.

https://clinicaltrials.gov/ct2/show/NCT04264533 [This official NIH site reports on the Chinese high Vitamin trial(s?) being run in China. A detailed explanation of other tests of high C that showed conflicted or confusing or weak results can be answered by reading the link above.]

[New York is the first area I have seen reported on that is now exploring the value of high Vitamin C in saving Covid-19 case lives. What they consider high dose may not come close to Dr. Cathcart’s experiences.]
As to saving a woman’s life? Here is the story. I was volunteering at a MASH tent for a large wilderness campout. When I showed up for my volunteer stint, they were trying to help a woman who had been stung by 3 yellow jackets in the neck (she had forgotten her bee sting allergy kit). Her eyes were swollen shut, she was choking and gasping, and her body was swollen all over. They had been giving her an herbal “rescue remedy” and it was NOT working. I immediately crushed 10 grams of Vitamin C, mixed it in a glass of water and had her drink it all. In 20 minutes her eyes were open, she had stopped choking, and the body was less swollen. I spent the next 8 hours with her giving 5 grams C per hour. Finally she said she felt better and thought she could sleep. I left her with a small bottle of C to take as she felt she needed. She hiked out 3 miles the next day. She never had the bowel tolerance symptom of excess taking a total of 50 grams in 8 hours. Klenner’s experience was with spider and snake poison.
