Cystitis is very unpleasant. I had a few infections , and always wanted wanted to wee! Each step I took felt like something bouncing on a full bladder. Really difficult during the night , regardless of bed time or how much fluid I took I was up on the dot every two hours to visit the bathroom, exhausting! As for car journeys it was a nightmare constantly needing a service station . Eventually my GP prescribed vagifem , a vaginal tablet now used twice a week. What an amazing change , I now have what I describe as a normal bladder. If on a long journey and I need the loo I can manage in a normal way ie , I need to go but it's not so urgent!! It has transformed my life !!
