I have had one fill 3.25 cc in 10cc standard AP band. I can still gulp food and not feel stuck sometimes.

sometimes if I gulp food I do get stuck but not always and its not really a bad stuck it just last about 15 seconds and then goes down.

I dont gulp on purpose. I dont sit there and say let me take huge bites.. but honestly im still getting used to all this and sometimes especially if I feel really hungry I forget to chew chew chew and just gulp it down

but I am wondering if this means I need another fill?

And to add to what Jack said, also don't do a hard protein in public. Not the prettiest picture, and not something you want your friends to witness. Once you reach the optimum restriction you will do whatever necessary to keep PB'ing from happening because it is not at all fun. You may need another fill or two or three to get to your sweet spot and then you will learn to be really cautious.
