My older sister has a terrible time with UTI's. She won't eat Kefir but has been having good luck with yogurt and OTC cranberry pills. I don't know what is available in Australia, here you have to be careful not to get the kind with Bentadine as an ingredient, there is a variety with cranberry only. A good quality Greek Yogurt (I like Fage) might help if you cant find Kefir.
I love Kefir as well but I tried it 3 times and each time it made my neuropathy hurt
. I have some immune issues from the steroid so am hoping I can try again when I recover from that.
