It took me almost a year to see the correlation between vaginal health and IC. I also started using boric acid capsules a year ago and that's when I noticed the greatest improvement in IC symptoms. I had issues with yeast/bv and the peroxide douch and boric acid helps tremendously. I also recommend Georges Aloe Vera distilled liquid for IC and IBS. It's very soothing and healing on the GI tract and bladder.
I'm happy to hear that you are doing well! IC takes the joy out of life for sure.
