Interstitial Cystitis miracle worker: loose leaf marshmallow root tea. Sold at health foods stores. Might be $30 a lb, BUT it's so light, about $5 can last a month. I am not a health food nut, but once I found it, I saw enough sites that I wanted to try. Now, I have a healthy tea to drink and between this, cutting back on citrus, and occasional prelief before a "risky" meal, I am off my 3x a day Elmiron with very rare symptoms. It helps quickly if I mess up with my diet and get a flare up.
