If you look around there are a lot of people that will say this gave them their lives back. From everything I have read here and elsewhere, the stools aren't urgent once your body gets acclimated to the new plumbing then the stools aren't "urgent".
I just had my Stage One Surgery a week ago. Honestly, I am doing freaking fantastic compared to wear I thought I would be. I have a loop diverting illeostomy which is taking a bit to figure out my skin but dealing with emptying isn't such a big deal.
You asked about nurses -- I am a physician. I work as a hospitalist -- so life is always hopping too. I wonder myself how it will effect my work life. I will let you know if you would like but I guess I will just figure out a new routine.
As far as drinking -- it looks hit or miss -- but you have to admit if you are able to work out, not be in the hospital and feel freaking awesome, alcohol over consumption should be of little concern.
I hope that helps a little. Hopefully more will chime in, also search the threads and you will find answers from previous posters.
Good luck!!
