After diagnisis I used to wake up in the night feeling alright, then get a jolt as I thought something was wrong. Then realising I'd got prostate cancer and then trying to rationalise it and it could go either way - thinking or going back to sleep.
Getting the date for the op was a turning point as from that time I was looking forward to getting it done. Nip into the hospital, go to sleep and wake up fixed. Then a period of healing.
There is some learning about catheters and pads and things. I was retired anyway, and we'd go for a walk and the first time the pad filled up fast due to the walking. So I was wet but my wife had a plastic bag to put on the car seat. After that we had spare pads.
Keep pushing yourself to do things but don't overdo it.
People are suggesting you look at other alternatives such as radiotherapy. In some cases that has some benefits but quite often it's personal choice. All the best, Peter
