My pelvic floor PT specialist said that nighttime incontinence is the most difficult to deal with. Things that helped me were limiting liquid intake after 8 p.m. and getting up to urinate one last time before turning out the light before sleep. You might also try setting an alarm for 1.5 hours after you go to sleep. Your sleep would be disrupted, but at least you wouldn’t be dealing with the mess, and maybe you could fall back asleep faster. Be patient. It took me about 3 months after catheter removal before I felt comfortable not wearing protective underwear to bed, and I would still wear it if I was very tired and felt I might sleep through the urge to urinate. Good luck!
