Hi:
I am a year post radiation(after surgery) and still have problems with thick saliva and swallowing. However, I have added turkey, pasta and salmon to my diet. It takes me a long time to eat about 40-50% of what I used to consume. My main drink is buttermilk as it is thick and easy to swallow.
You may have to experiment awhile to determine the types opf foog you can handle. Good Luck.
