From where I came from, there is a saying; may a bad thing happen for a good reason, that's exactly what cured me, plus the wonderful vitamin E enema by Sheldon (by the way Sheldon you are a great person), but before I start I would like to say that English is not my native language, so forgive me for any language mistakes.
I had UC 5 years ago, Diarrhea, bleeding and pain, my condition was severe, but by the time I learned that eating certain food and getting away from other makes my condition less severe.
Until a year ago when I discovered the Vitamin E enema by sheldon, I used it and it really did ease my UC, much less bleeding and diarrhea, I was sure that it would cure my UC but for some reason it did not completely cure it, I think I did not do the procedure right or something was missing.
My second part of the story was 2 months ago when I had a facial nerve infection, and the primary medicine for it's treatment is Prednisolon, I started taking the medicine and on day 3 I started to see well formed stool! I was shocked because I didn't expect that, on day 12 (the last day of the treatment) there was absolutely no diarrhea or bleeding! completely normal bowel movement.
I sent an email to a friend of mine who is a doctor and told him about my story, he told me that Prednisolon does cure Ulcerative colitis, but doctors do not give long term Prednisolon as a treatment for UC because it has a lot of side effects.
So what happend exactly in my case is that vitamin E enema cured a big part of my UC and that gave the Prednisolon the chance to cure what is left of it in 12 days treatment (before it's side effects occur).
The conclusion is I do advise to try Sheldon's vitamin e enema, it does cure UC, and if you had a similar case as mine, maybe you can ask your doctor about Prednisolon and if it can help you in any way.
