You seem to be doing well. You should find that the bladder will stretch over time and you can last longer. I can go about 4 hours now. You might also find over time ( and its years) that your body starts to develop the ability to detect a full bladder, almost like it did with a normal bladder. It seems that the weight of a full bladder can trigger nerve endings to send signals to your brain, not unlike the tingle you used to get.
In theory removing about 9ft of the colon to make the bladder should make little or no difference to your system. But in practice, I found that it certainly did. You might get back to normal soon, but as my system recovered it got into a cycle that has remained almost the same for over 20 years. Three to four days of constipation, 3 to 4 days of normal stools, 2 days of loose urgent stools finishing in diarrhea, which cleans me out, then the cycle starts again. Surgeon has never been able to understand it, but it has never changed. It can be a nuisance, and occasionally embarassing, but never seems to have done any permanent harm.
