Rick,
The 2 hours is usually just for the initial stretching time. You should have received a schedule for this when you got the catheter out. Your night time waking usually aligns with your day time schedule. Two hours at the beginning and then progressively longer (both day and night) over time a few weeks to a few months to stretch the neobladder.
Here is some information you may find helpful:
Webcafe: Continence with Neobladder
If you are really suffering from lack of sleep, you might try a condom catheter for a night. As long as you aren't hypercontinent (which you're not if your leaking a lot) it should be OK to do one night and sleep through the whole night. I know it can be frustrating waking up so often. I used to wake up every hour to hour and a half before getting my surgery because of prostate problems so I'm pretty glad that problem is over.
You may also want to consider the condom catheter for other nights but still wake up according to your schedule to empty the neobladder. This way you aren't all wet. Any night time leakage will just go in the catheter bag. It is WAY better (IMHO) than waking up all wet and dealing with the whole diaper thing.
I've heard bad things with the ones that have the wrap around strip if people put them on too tight so I just got the ones with wide band adhesive.
Here is a link for your consideration:
Condom Catheter
Just disconnect the catheter bag from it when you wake up to go and reconnect it when you get back in bed. Hold the hose up when you disconnect so that any urine in the hose can drain into the bag and the bag has a valve so it doesn't come back out into the hose. What I do is buy the 18" extension hose for the catheter bag so I can just toss the bag on the floor and it gives some extra length for moving around in bed.
I know you asked only for opinions from people who achieved full night time continence and I am not one but I thought I would at least put this out for your consideration.
Sorry you feel having surgery was a mistake. As for me, I'm glad I did and I always try to encourage people to get to the best surgeons with the most experience in the diversion of their choice. That way fewer people have the kind of problems that you and others have had.
Good luck with getting this all under control.
Mike
