Hi there!
I was also banded on 3/1/10. I can't burp either, but I've been farting like crazy! LOL! I've read on here that its one or the other. Remember to take sips of Water. I forgot once and took a big gulp....oh boy...it was a very uncomfortable feeling. Each day will get better. Yesterday was rough for me, but I feel much better today. Remember...one day at a time!
