Your surgeon's lack of experience is showing in the way he is communicating to you regarding what your expectations should be post surgery. At your stage in the game, I was a long way from recovery, and was eating only tiny amounts of food. As I said, the reflux should calm down, but not after the swelling goes down and healing has progressed.
While it is too soon to discuss a redo, I can understand your thinking about it, and I don't think it's a totally bad thing to consider. I also determined that I would have a redo if necessary, early in my recovery. As I've said, I was coughing hard and nonstop because of asthma/lung infection, and I knew that I was likely doing damage. With me, having reflux is not an option. and I very well may have a redo at some point. I'm now going to an asthma doc who is exploring what's going on with me, and is very suspicious that I did damage to my wrap and am getting enough reflux to get my lungs going. (I guess it doesn't take much.)
At this point, you just need to go with the flow. Give yourself a chance to see what your results are (it will take months) before jumping the gun. Take whatever meds you need to be comfortable, and just heal.
