It sure sounds as if your wrap is too tight. At eight weeks, it's common to still need to move back and forth between easier, softer foods, and more normal diet, taking tiny bites and chew, chew, chew. Gradually over the first four months,though, you should be moving toward less difficulty eating.
I believe it is totally unrealistic of your surgeon to expect that your swallowing won't improve for 6 months. That is definitely not typical. Yes, you will need to eat more carefully, but you should expect to be able to eat more than liquids or soft foods at this point.
That said, everyone is different, but it's still hard to believe that it isn't too tight.
Hopefully somebody will be by who has experience with this particular issue.
Good luck, Lexilu. Hopefully things will continue to get better.
I assume you aren't drinking from a straw, or having carbonated beverages. I was also told that I shouldn't talk when eating, as it would cause me to swallow more air.
I am sorry you're struggling like this. Hope things turn around soon.
