Hi DJC44,
As you have acknowledged, experiences of incontinence vary widely. Some people are dry almost immediately.
I had really bad incontinence immediately after catheter was removed - used about 8 pads a day for the first 3-4 months. I'm now 20 months post surgery and use 2-3 pads per day on average. However, I was pretty dry lying down at night from the beginning. My Urologist told me that this was a good sign, as it implied that the problem was 'mechanical' and should improve with the Kegel exercises. He also referred me to the Pelvic Floor Physiotherapist to check that I was doing the exercises correctly. (I was, but they reported that my muscles were weak). It might be worth your while to ask for such a referral if the Urologist hasn't already done so. (Like everything else, there is a waiting list).
I have been doing Kegel exercises throughout and added in Pilates and Yoga, which I attribute to the improvement as much as the Kegels. I also go for walks about 3-4 times per week. It is very difficult to figure out what makes it worse. I can have a few good days when I think I'm improving, followed by a couple of bad days, when I seem to be standing still. I've cut out all the obvious things - e.g., caffeine, carbonated drinks, citrus drinks, long drinks (e.g. pints of anything!).
I try to get on with life. I always have a spare pad with me whenever I'm out and about, and it doesn't stop me doing most things (except swimming and using shared changing rooms).
Hopefully, you will improve with time.
Good luck.
