While not reporting a cure, there is a book on Amazon that has a lot of information on the use of Methyline Blue - it's not very large nor expensive, but has information on dosage as well as numerous conditions it helps.

There are a few and most are pretty poor. The best reviewed one by Mark Sloan is "The Ultimate Guide to Methylene Blue" for about $US 4 on Kindle which was worth getting I found.
