Good Afternoon Deni!
It's the final countdown to your big day. I'm excited for you!
It appears you're ready to go. The toileting may not be as difficult as you're anticipating. I found not much of anything as daunting as I imagined it would be.
I slept in a recliner for three weeks...amazingly well. I normally had one bathroom run in the middle of the night, then back to sleep. I was surprised and felt well rested.
A tip you may have read here somewhere, but in case you haven't is to make use of trash bags. When it's time to head home from your surgery site, a garbage bag on the car seat you will help you easily swivel to windshield facing position. Also, a trash bag is handy again when you do decide to get into bed because it will help you easily move in from the edge of the bed, toward center, removing friction between sheets and bed clothes.
I will be thinking of you and lifting you in prayer

for peace of mind, an uneventful surgery and easy peasy recovery.
See you on the flip side soon!
