has anyone ever used the product Cystex? i know that there are other products out there that ease the burning pain of a uti like AZO Standard, which i've used before and was happy with, but i was looking online at my local drugstore and saw that they have this product called Cystex. its supposed to ease you of your pains and help control the uti. i read some reviews and people said it was amazing and it was the right product for people with cronic uti's. i just wanted some more opinions about it before i go and spend money on it. thanks!:D
