Did You Wake Up to Pee, Or Decide to Pee?
Think about your last nighttime trip. Did your bladder wake you: sheets-off, no-choice, now? Or did you wake first, lie there a moment, notice some pressure, and think: "I'm up, anyway. Might as well go."?
Both feel the same by morning, but only one was the bladder.
The other was sleep that broke on its own and your bladder simply volunteered as the explanation.
Next time you wake up, ask yourself: Did I feel the urge before I opened my eyes, or after?
