Ed, I started out just as you are doing. Depends Pads during the day,and Depends underwear at night. About 4 months out I was continent, and quit wearing pads during the day, and switched to pads at night. I am now almost eight months out, and still wear pads to bed. I get up once a night to void, and I am anywhere from dry to damp come morning. I am never soaked. I attribute my improvement to physical therapy.
Here are some exercise's that have really helped me.
I do the roll ins (with the ball), and roll outs (with the strap) daily. I will continue these for the next year, along with kegels. A small price to pay to be dry.

As far as mucus, it has improved but is still there.
I drink minimum of 64 oz of water a day, and at least
16oz of cranberry juice. This seems to keep it "thinned" out.
I also take Zantac twice a day. It is for heartburn, but it has proven to help thin mucus as well.
I void every 4 - 5 hours, and it's about 300 - 450cc.
Also 50 -75cc post void, self cathing.
Hope this helps, Jim
