FYI - Artificial Sweeteners and UTIs

Im not sure if anyone has this problem but since I was a little kid I've been prone to UTIs (urinary tract infections). Anyway, I've been having them a lot lately for no good reason, and I have a friend who is an acupuncturist who suggested I take this stuff that works really WELL! And she just told me also that artificial sweeteners (i.e. crystal lite!) irritate your urethra and to not drink them when you're healing from having a Urinary Tract Infection. Also it's possible that I've been having so many because I drink crystal lite in my water every day! I was so bummed. Anyway, I dont know if any of you are having this problem, but I thought I'd let you know. Have a great weekend!
