First of congratulations on your surgery date!! Happy dance time!!
I had my gastric bypass about two weeks before Thanksgiving. I was worried about what I could eat at the meal, but it was a total non issue. I spent the meal enjoying lots of family conversation and I didn’t have that awful overstuffed feeling afterwards. Nobody cared what I ate or did not eat. Oh, even though it wasn’t really on my post op diet plan at that time, I did have a small piece of turkey breast at Thanksgiving which I ate in very small bites with a bit of gravy (chewing it into a paste before swallowing).
The major change for me that year is that I came as a guest in that I had other family members do all the cooking (I am the cook in my family and usually cook everything for a 10-12 people traditional New England Thanksgiving meal). The following year I returned to my normal Thanksging cooking duties.
Once again, congratulations.
