If you want a good range of experiences with an AUS check the discussion here titled: "Can Someone help me about life after AUS 800 implant?" Posted by rodneyverrill.
I wish you and your wife all the blessings that can be. I lost my wife and sweetheart of 53-years to Covid (and no immune system due to a 20-year struggle with MS) a little over 2-years ago. My RALP for early but aggressive PC had to happen 2-weeks after she passed. That didn't help. Both recoveries take time - way more than I expected or realized.
You've gotten this far and you're able to ask cogent and meaningful questions. You're tough and thoughtful, keep it up and God Speed to you both.
