My direct mail gets rejected, so have to answer to the list.   Mike; do a 
google search for d-mannose. 10 to 50 times stronger than Cranberry.  Here is 
the way it is supposed to work:
Much in the same way cranberry works, ClearTract(brand of d-mannose) interferes 
with the ability for bacteria to cling to the urinary tract lining, this is 
sometimes called the "anti-adherence effect" ClearTract is the most potent 
"anti-adherence" compound for the urinary tract known and accomplishes more 
than cranberry has ever been able to achieve. use http://www.froogle.google.com 
to search for a good price.
