I have only recently started the burping thing. Only since my last fill a few days ago. But its not always a burp...i feel like i have to and when i try and burp, i can feel a little bit of what i'd just eaten come back up a little to the back of my throat. Of course swallowing after i burp. This can go on for like an hour. I don't know if its the restriction and i ate too much, hense coming up a little when i burp...i know the food isn't "stuck".. as i've experienced that too and that is very painful and made me naucious and puke. This is different.. just kinda feels weird and maybe full...hense maybe why i constantly feel as if i have to burp and when i do, a little food comes to the back of my throat. Am i making sense? does anyone know what i'm talking about?
