Lol that's funny, we have almost the same screenname, and in a different forum, I suggested azo cranberry pills to a pregnant woman with a uti.
As i'm sure you are aware of, if you do get another uti, the drug pyridium is a godsend, although the color change of the urine does take some time to get used to o_o...
I also hear that some people are sensitive to getting uti's if they drink alot of caffeinated beverages (tea, coffee, soda, etc.)
