I am not sure if your Nocturnal Anuresis (sp?) is related to IC or something entirely separate. I have (well - "had") IC and I have experienced night time frequency. Its absolutely horrible!

You may call their clinic and see if this treatment is something appropriate for you. I can understand how difficult something like this can be for someone so young. Good luck!
