Hello I am a 61 year old female with ICS of the bladder. I am on Elmiron (over $800 per month not covered by insurance) and take AZ0 over the counter since I cannot afford the Urelle. I have a stim implant that does help with the urgency, frequency and accidents. Since the dietary rules are so strict, I am concerned about taking vitamins. I shy away from vitamin C, and I do use prelief before eating or drinking anything acidic. Any advice? Donna N.
