I have the knowledge that I have been suffering from recurrent post-coital cystitis for more than 10 years.
Always treated with antibiotics, I realized it could no longer work because the episodes of cystitis were becoming more frequent (up to once every month).
With internet research, I learned about Dimann products. Initially I took only Dimann Pure after intercourse, then I added Dimann Daily, Diman Candida cream, and Dimann gel lubricant to minimize episodes of infection.
Now, cystitis only happens to me in times of high stress, normally only once a year.
Thank you Dimann!
