You are relatively young and I'm sure the fog will gradually lift and the mind will clear.
Beside that there is another condition that you should be aware of. The pain meds and anesthesia can often cause temporary constipation, and you are showing some classic symptoms. My advice would be to make sure you have something on hand to remedy that situation. I.E. colace, senna, Miralax to name a couple.
Bring it up with your Doc. You can thank me later when you are up and running....
