Michael,
I use condom catheters every night but I'm two years out and do not expect to ever acheive night time continence. I do not recommend using condom catheters in the early training phases, so I agree with your doc.
The only time I do is when someone is talking about being so sleeped deprived or so fed up with the wet undergarments. In the case of the former, only wearing it for one night to get some sleep. In the case of the latter, wearing it, but getting up in accordance with the schedule to empty anyway. Even then, not to use all the time. Reason being, it gets too easy to not worry about it if you have a condom catheter.
I know you are already planning on listening to your doc so this is more information for other people who read the forum.
