A friend had to use Depends for a period of time after his prostate surgery, but eventually his bladder control was regained. Hope they get the light headedness cleared up. Keep up the good progress.
We just don't bounce back like we once did. It takes some people longer to recover from the effects of the anesthesia. This may be what you are experiencing. Sounds as if you are handling the 'indignities' well, and glad that you are having no pain.
