Nausea!
Are you on a PPI? I had the same problem and that's how I discovered my reflux.

I was on one too and ended up needed something stronger. If it keeps up, give your surgeon a ring.

Try this: put a little bit of soda in your water or pour your water over a bit of fruit/lemon or cucumbers/mint and leave for a few hours. There is a something about surface tension of water that makes it harder to drink early out. I had to find the water with the right pH for me and could only drink if it was infused with something else. The issue eventually went away.
