I had sarcoidosis when I was twenty five. It went away on its own. I did take 100 times the minimum daily requirement for vitamin c for several months (lots of water also).
You were lucky. The recent NIH Access study did not did not find any remissions longer than 2 years.
I am a huge fan of Vitamin C that one would think I sell the stuff or own stock in a company making it. It's worked miracles for my rheumatoid arthritis and other problems. I've been reading a lot about intravenous Vit C, too. Wish I knew of someone to administer it, if I ever need it.
