I can’t thank you enough for responding to me, I am sooooo panicked!

you're not going to feel the restriction right away. First of all, some nerves were cut during surgery, and it takes awhile for them to regenerate. Secondly, most of us don't feel restriction until we start eating solid food. For now, you're going to have to measure your food and just eat whatever you've portioned out (following the guidelines given by your clinic). It's hard because you're not going to feel "full" for awhile - but just eat what they tell you to eat.
I highly doubt you've stretched your pouch - it takes chronic overeating to do that - but don't get back into the overeating habit. You're just a few days out. Trust your program.
