Hi Pete,
I'm exactly one week ahead of you. I had my RP surgery last Monday (the 19th). One week later and I'm already feeling a lot better. Definitely take it easy the first few days. The morning after my surgery I was feeling well enough to do some walking in the hospital corridors. I walked and walked and pushed the nurse to let me do more - and then out of no where I was hit with sudden dizziness and passed out cold on the hospital floor which resulted in me being kept in the hospital an extra day. I'm not trying to scare you. Just be a little extra cautious the few days. I find I can be feeling really well and then suddenly get winded - but 7 days out this is already improving significantly.
Funny coincidence, but I too was diagnosed with a small hernia which was picked up on my PSMA PET scan a few weeks ago. I asked my surgeon if it could be repaired during my RP but was told no.
Anyway, hope all went well and best wishes to a speedy recovery.
-Mike
