Now would be a good time to find out if the doc will give you some meds to relax prior to surgery. My ex had this done, but his doc did not give him that. I found out from a friend that the doc her husband had...did give her husband something to relax.
With Meds, it really was not a big deal for my ex to get over the surgery. I think the surgery itself was the scariest part for him. Fear of fear ya know?
The pre-surgery exam is no fun. But not a big deal if you have had that done before.
Avoid anything that will give you a "ou know" after the surgery.
Milk it for what you can get. Stay in the bed watch TV...sleep. Take the nice meds.
