Hi Anita, as long as you are able to liquids down and they are staying down, I don't think you need an unfill. Certain times of the day, certain times of the month and certain foods get stuck for me too.
I drank a Slim Fast for breakfast, some sheppard's pie for lunch and dinner was a write-off, ate about 1/2 a homemade burger (no bun), chopped really small, but it got wicked stuck and I couldn't eat anymore or anything else.
I can't eat in the morning, I am really tight..but lunchtime seems okay so far, dinner comes and goes. I would monitor it and if you are not able to eat anything without it getting stuck or PBing, you may need a little unfill.
Good luck sweetie..I know it's not fun...but it does loosen up over time.
Take care!
