Seirla, that's good news. Remember to finish the entire course of the antibiotic. Don't try to save some for next time, even if you start to feel much better after one or two pills. If you stop too soon, the pouchitis bacteria might come back with a fury, faster and stronger than before.
Maybe ask your doctor if your prescription could have several repeats on it so that you just go to the drugstore and pick it up when needed, without having to contact your surgeon and waiting for them to call it in to the drugstore. Also, if possible, maybe start something for yourself similar to a "home fund" but in this case make it your "health fund". Each month put aside just a couple of dollars into an account that is only for emergencies or medication in case there is a holdup in your insurance again. It will ease your mind if you know there is small fund for emergencies or medication, as a bridge to help you through.
Keep getting regular pouch checkups with the surgeon who made your pouch. She will know it best since she created it. Maybe they will let you book a year in advance, just to get into their schedule.
