I used to not have any problem sleeping through the night-if something was on my mind/plans for the next day, I might wake up an hour or two early. Now however with my kidney issues, I wake up a couple times a night to pee. I take a Tylenol PM or whatever Walmarts version is every night, and so far, I don't have a problem going right back to sleep in most cases.
Thankfully my cat lets me sleep, and has learned to stay on the far side of the bed so she doesn't get blankets thrown over her when I get up to pee.
Growing old sucks
