My takedown was pretty easy. I'd also read the bad things people said; about how going for the first time would be like "shitting glass" etc but none of them happened to me. They gave me a day of no food, then a bit of food to get things going and then I was out on day 3. Pain wasn't an issue. No catheter.
I was cautioned against immodium at first. Your guts stop in shock after the op, food gently gets them going again, you don't want to then be taking immodium to slow them down again. I was sure I would be taking immodium with the J Pouch but I discovered it makes things too thick and difficult to pass so I just don't bother any more.
Gas/food pain a bit of an issue at first but goes after a week. None since.
I just use a bit of wet toilet paper - cheap and easy. There was some butt burn for a month but now there's nothing.
If you coped okay with the first two ops, this one will be a total walkover
