4th fill and I feel looser-wtf???

I had surgery in Oct 2008 and lost 85 lbs so far, about 30 to go. I just got my 4th fill last month and now Ithink I feel looser. I told my the Physician Asst that I had been experiencing a little heartburn since I had been PB'ing and she said she was only gonna give me a 1/2 cc. Well, since then I can eat more and I cant throw up. Not that I want to, but if something feels stuck now, I cant get it out. My question is: Has anybody felt looser AFTER a fill and able to eat more???? This is pissing me off, cause Im not losing and keep goin up and down 3 lbs. I can finish a tuna sandwich without feeling uncomfortable. Yet, I cant eat a slice of pizza or have Chinese rice. what gives? I know, I know.I shouldnt be eating that stuff, but can someone answer my question?:laugh::wink2:
