I did this for IBS. It helped me out tremendously - it didn't cure me, but it allowed me to go on vacation at a time when I was hitting up the bathroom 10 times a day.
Funny side note - my poop has no smell. For quite a while after the transplant, mine smelled like the donor's. It proved that it took hold, for a month or two at least. Now I take Cholestyramine every day, and that has helped even more.
While you have been down voted for expressing your "nope" opinion. I think a proper way to handle this would be to add some sort of warning/tag before posting links to content which may shock/offend etc.
