LDN as Alternative Treatment for Crohn's?

A friend recently alerted me to the fact that low-dose Naltrexone (LDN) 
shows promise as an effective treatment for Crohn's disease. The home page

for information about this treatment is as follows:'

http://www.lowdosenaltrexone.org/

Lest people think that this is just another example of
alternative-medecine 
quackery, the page features a re****t of a scientifically sound study done 
last year at Penn State University--and re****ted in the American Journal
of 
Gastroenterology--that re****ted success in a limited trial of this 
treatment. Here's a link to an abstract of that article:

Even if one wanted to try this treatment, there are two hurdles to
surmount: 
finding a doctor willing to prescribe this off-label use of the drug, and 
finding a compounding pharmacist willing and able to make up the 
uncharacteristically low dose. If anyone out there has tried this
treatment, 
please post your experiences. Thanks.
