How long to regrow a fresh cellular lining of the bladder?

My urologist’s NP told me that my bladder muscles are “road-burned” from a combination of r/CUTIs for 2 years and all the antibiotic courses prescribed for these infections to the point where I am showing antibiotic resistance to multiple strains of bacteria.

They told me to drink nothing but water for six months—no coffee, no tea, no juice, no smoothies—absolutely nothing but plain filtered water. I think they said that after six months, my bladder lining would regenerate and would be healthier and not “rug burned.”

I am 2 months in to the water-only protocol and haven’t cheated even once.

I’m wondering if anyone else has gotten this type of advice from their urologist about how long it takes to regrow the damaged lining of the bladder, and the drinking only water in the interim.

Thank you for sharing!
