Wow- 3 liters of water you must drink non stop? Scary and sorry to hear you lost a kidney.
Does the bag stay on if in the pool an hour or more? I love to swim and that would be life changing to give up. I am sure suppliers tell you it works just want to know from someone who really swims with ostomy the truth. And I have super sensitive skin, could never tolerate any adhesives. Always need to wrap wounds with Ace & bandages. So not sure if I’d tolerate a bag adhesive. It’s giving me nightmares as I’ve had sling breakdown with any bandages
