Awweeee, I am so sorry to hear that you are now little bit down due to incontinence worry :((. It will get better, you will see. I know it is hard but you have to make sure to find a way to relax and give your body time and energy to heal. You are really so early in your recovery path.

Regarding PT and this doctor's advice - if it was me, I would try both ways and see what works for ME, no matter what anybody says. ; ). We are all different and we know our body the best. It is especially hard concept for men to grasp since man do not pay attention so much to bodily functions and are actually culturally trained not to pay attention. If you had a better result with less water before you started PT than 2.5 might be too much too soon. What if your bladder was naturally smaller than average and is now even smaller after surgery ? Making extra pressure on the sphincter that needs time to get strong can not be good. Talk to your PT and explain that you had better control before you started PT and perhaps share this video. Just take it easy and be kind to yourself, you are expecting too much too soon < 3. IF you ever come to 12 mos and you have a problem than there is a solution for that too.
