For me, it's been 23 years since the big trouble hit, and 15 since the sarcoid diagnosis. I never saw anything that said vitamin C would help, though I did try it along the way for symptomatic relief, though not at the doses you mention. It didn't seem to help much.
I have found that the antibiotic protocol I'm on is getting rid of the sarcoid. A lot of the other getting-old-fast stuff is going away too, like cholesterol and triglycerides and insulin trouble and high PSA tests.
The next question would be if you have any other auto-immune trouble like arthritis, or diabetes, asthma or psoriasis. The current research suggests that these are all tied to the same set of infections.
Not that I know of.
57 years old, blood pressure is about 120 over 80.
Exercise enough to totally sweat up four to five days a week.
No diabetes, asthma, or anything else that I know of. Thumbs are a little sore maybe arthritis is beginning.
Red wine or beer on weekends only after 5:00pm. Still take lots of vitamins. Plan to walk the Appalachian trail in three years when I retire.
After all this I'll probably have a stroke or something next week.
