My prostatectomy surgery is in two weeks. How should I best prepare for it?.

The C/T and Bone scans showed no metastases. I selected a surgeon who uses the DaVinci machine. I am already doing Kegel exercises. I am keeping my weight at its normal healthy level. I’m in my mid 50’s in (what I thought was) perfect health.
I feel the clock is ticking but I don’t know what else to do. I’m open to advice. You can contact me privately if you don’t want the public to know. You won’t get points but you’d be helping a lot. My mind is in a bit of a jumble now.
