Hello. I had an interesting experience yesterday regarding this. I'm 5+ weeks out from my RP. Catheter was removed after 1 week and I've been pretty much continent...only small leaks now and then if that if I drink too much water. I even stopped wearing a pad a couple of weeks ago.
Yesterday, I was up early, had 1 cup of coffee and went to the gym. I walk, lift light dumb bells, and do kegels..those daily. I would say I had a good base of fitness before surgery and I'm bouncing back OK.
I then attended an event where I was on my feet for roughly 4 hours with a break for lunch. I used the rest-room when needed and drank a bottle of water with my noon meal. No issues.
Afterwards, I attended a birthday party where I had my 1st drink (an old fashioned) in over 8 weeks. I was startled that I experienced incontinent issues while there...even while sitting. Good thing I wore dark pants. I didn't have a pad on but did have one in the car for emergency in case I needed it and frankly I almost ran out and put it on.
Question is...did the alcohol kick this in? Was it the standing in combo with the walking and light workout? Was it lack of sleep? All of the above?
I certainly don't know what caused your issue, but that sounds like a lot of activity for only 5+ weeks after RP. I'm 13+ months after RP and I remember the first several months as having several surprises regarding occasional instances of minor setbacks. I remember reading something to the effect that when the internal swelling starts to go down during recovery (at 6-8 weeks) some guys will experience an increase in incontinence without the "swelling assist" in maintaining continence. I know I experienced that at about 2 months post RP. Long story short, although I was essentially continent after surgery it has been a journey of figuring out the new normal. Definitely not a straight line progression. One last thought; doesn't an Old Fashion have a variety of things in it besides the alcohol? Maybe all of them (including the alcohol) contributed, coupled with a bit of pelvic fatigue from such a long day. Best wishes.
