Always go pee. Yes, it's annoying as hell to crawl out of the comfy bed again. But it's even more annoying to wake up a couple hours later with an even fuller bladder - or even worse, to wake up with an emptier bladder.
It's common enough when younger. It stops in teenage years to middle age, then starts again in old age.
Do some kegels to firm up that pelvic floor. Drink less water before bed. If you can, remember pissing in dream means pissing in bed. Wake yourself up before you mark the sheets like every drunk lush of a woman I've slept with.
I had to learn to remember this within the dream and to forcibly wake myself up from it to stop this happening. Which I think is quite an accomplishment, if I may say so myself.
I suspect it goes back to wearing nappies/diapers as a baby. Babies naturally try to wait until they are unclothed to relieve themselves; they essentially have to learn how to go in a nappy, or else let it happen because they can't hold it in any longer. Then they have unlearn this with potty training. It's crazy really.
I've often risked it. So far haven't had the accident happen. Can't be arsed to go every time since it takes me a while to fall back asleep if I get up
Just roll over lift the bllanket a little, and pee into the kiddie pool you keep next to your bed for late night peeing, and early morning foot baths, don't people know it prevents athletes foot?
Why not both? "But how?!", I hear you say. With a magical device known as a catheter, of course! Simply insert the receiving tube into your urethra and then go to sleep knowing you won't wake up in a puddle of your own leavings.
All those things sleep experts tell you to do in order to fall asleep faster and sleep more soundly? Pee should be at the top in the middle of the list, right before the part where you get ensconced under the covers.
Edit: if you get up for a crying baby, pee again before you go. It might go back to sleep, but mostly, once you pick it up you'll not get another chance to pee, maybe for hours.
My asshole body: yeah I know you peed before bed but it's 2 hours before you need to be awake so you need to pee now. Oh the time you went to bed changed and the time you need to be up changed? Doesn't matter, 2 hours before you need to be up I'll wake you up to pee. Good luck getting back to sleep!
