Besides a UTI, there is another possibility. The narcolepsy may be resulting in a very deep sleep that's preventing you from waking up when you need to go. If you are on Spiro, you should consider taking your last dose long before bed time so most of it's effects have worn off by then. Another thing is to have your last fluid intake a couple of hours before bed time and go to the bathroom just before sliding between the covers. I have never had issues with bed wetting but I have had wake up calls because of excessive fluid intake before bed. If you tend to wake with a dry mouth at night. Put a glass of water by your bedside should you need it in the middle of the night.
