Welcome to the Healing Well Wrapped Club! I suspect you were on IV fluids in the hospital, which could explain your weight gain. I'm sure that as the weeks progress that weight will begin falling off. Glad you've joined the forum...this is a great place to get support and answers.
Here's a link to my early recovery journal, so you can get an idea of what the recovery was like for another person. I had the surgery a little over four years ago.
I don't know if your surgeon warned you, but your wrap will become increasingly swollen over the next two weeks, peaking on or about the 14 day mark. Don't be surprised if your swallowing gets worse before it gets better. That's probably why your surgeon has you on a liquid diet.
