I have a really weak bladder, I wet the bed more or less every night until I was like 8 or 9 years old, it was really bad, my parents tried everything and eventually one of them would come through after I'd been asleep for one sleep cycle (~4 hours) to wake me up, take me to the bathroom and then I'd go back to bed, and that was how I stopped wetting the bed. Now, as an adult, I still have a really weak bladder and am forever running to the toilet, I always pee when I arrive and before I leave at any kind of destination and if I've been drinking alcohol I always wake up after 4 hours, go to the toilet and go back to bed. It's pretty strange but my parents were doing this for a long time to get me to break the habit so I think it must be deeply ingrained in my mind now
I'm so sure I do heaps of weird things I just can't think of any right now
