Yeah, I just had mine four days ago.
I'm feeling pretty well, if somewhat low-energy. Just acetaminophen, despite "autism dangers", is enough to control any belly pain, which has been minimal. The nurse during discharge was super helpful and loaded me up with all kinds of drugs and accoutrements--don't really need much of it!
I haven't been out and about much. My understanding is that it's ideal to not change catheter bags to minimize chances of UTI, so I just have the larger bag connected, hiding it discreetly in a plastic shopping bag when I do walk around outside. It seems to last the entire night, so I can just empty it in the morning. I do have a wife providing support.
Took me two days before I could move my bowels, also little to no appetite, even now.
I don't have any special continence provisions--I think that comes into play after about 10 days when the catheter is removed. Like you, I've been doing Kegels, so I hope to regains control before long. I've been advised NOT to drive before catheter removal--whether that's due to being vulnerable due to a tube sticking out of me, or the potential hazards of tubing getting snagged amongst pedals, I'm really unsure.
I swear that the worst thing at the hospital was being barked awake at 6am--I am NOT a morning person--to order my breakfast, served a couple of hours later. Hospitals are notoriously hard to sleep in, although I had a private room, which was really nice.
Sorry I'm kind of rambling. I am still feeling just a bit spacey--after effects of general, perhaps? But based on my experience THUS far, I'd say don't over-think it or over-worry it, it doesn't seem to be that big a deal. You'll be a bit stiff, sore, and slow-moving for a few days, but ultimately we're both going to beat this thing--we have similar health outlooks I think, and, hopefully, regain most of our prior capabilities. I think the nervous anticipation, which is to be understandable, is worse than the event itself, so try to be calm about it, and relax...
