What kind of catheter do you have? I have experienced 2 blockages so far, but have heavily increased my fluid intake and also added lemon to my water (60 mL LJ/ 900 mL water) in the morning and at night in an attempt to keep things flowing well. I am really hesitant on doing catheter flushes because I don’t want any more exposure to germs than I need to, as I have no spleen and feel prone to infection.
