Alf,
Seeing as we are about the same "time on the path", I guess comparison is valid.
My pad use went from one per day pre-RT, to three pre-day post-RT, then slowly got better (back to one most days) over the following year. But the last eight months or so I have been backsliding. Now I am back at three probably 25% of the time.
My uro credits the long term effects of RT.
