I know getting up at the most 4 times is alot and it will ruin the next day. I used to get up more than that.
But even not having a pouch anymore I still get up 1-2 times a night. It's definitely alot better than it was I had some serious problems with my pouch. No sleep was one of them. Side effect. But if you can get it down to 1-2 times a night I think that would be normal and about the best your gonna get. I hope that doesn't sound disappointing. I get good sleep even getting up twice. At my age even if I had a healthy colon I'm gonna get up once a night. And I limit what I drink before bed. How much I drink anyway.
Good luck. I do hope you can get your nightly interruptions down. It does wear on a person. I know it does because I went through it for years.
And sleep is very very important to keep stress levels low.
(just trying to put things into perspective from a person who had his pouch removed. I do not suggest that to get sleep lol)
