I am of the same mind. I just started LDN a month ago after a sudden onset of a severe flare.
My Rheumatologist Rx'd it for CD related tendinitis in my shoulder, when I did my reasearch I found out about the Crohn's study. Keep in mind that study is limited and there is double blind going on for CD which should be done by July 2010.
Something else to consider: I used the MS protocol. So I started at 1.5 mg and worked up to 3mg -- LDN is both weight dependent (3% of body weight) and effected by metabolism, mine is high so I may go higher, but am staying at 3mg for a few weeks to give it time.
LDN does take time to show results, but that's true of all the drugs, so...
I did notice improvement in my shoulder at the lowest dose, in terms of the pain -- it localized and stopped radiating. Range of motion has just begun to increase in the last week.
As for the CD, well my appetite is better, but my body's ability to process is complicated by an abscessed fistula, still my pain has come down and I'm willing to give it some time.
I've never responded well to the immune suppressants, and Humira is the last for me. As I have this abscess and I'm not sure I trust Humira with that problem, I'm going to put that on the back burner for now.
Check this out too, there are some podcasts full of information, and a forum there too.
