Sorry that you have to be here, but welcome to the best PCa forum on the net.
It is my understanding that most men leak for around 2-3 month after the catheter has been removed. A few men are lucky and are dry very soon after removal, but some are not so lucky and will leak for much longer. We're all a little different.
Little or no leakage at night after only 5 days is a good sign that you might be dry in the not to distance future.
Do you 'kegels' and walk as much as you can without straining to much. One thing you will have to learn with this disease and that is patience.
All the best to you in your future.
