Make sure you have a comfortable "healing space" set up at home. Pillows, blanket, and entertantment.
No lifting anything over five pounds for six weeks and then gradually add five pounds a week after that.
No bending over for at least two weeks- you'll regret it (Ouch!)
Make sure your doctor gives you some liquid anti-nausea med and liquid pain meds before your surgery date to have ready on hand. So there's no last minute rush to the pharmacy that night.
Have some liquids handy for you the first few days. Ensure, boost, slim fast, vitamin water, gatoraid, broth, jello, fruit juice or popsicles.
Plan for at least three weeks off work. I did two, but really needed three.
Relax and go with the flow. :)
