I have been banding for almost 2 years. I spent a significant amount of that time unfilled. I working my way back up with my fills. My last fill was over 2 weeks ago. Today, after two bites of lunch something got stuck. I heard that "gurgeling pipe" sound in my throat and felt the tight ball in my chest. I have thrown up 4-5 times in the last 3 hours. The first few episodes, not much came up. But the last one (5 hours after eating) was a dark slimmy liquid. Is this a PB? I have never experienced PBing but I had the impression that it was something that happed soon after eating, not 5 hours of pain later. I feel a littel bit better after the last vomit but still feel a painful "ball-like" feeling in my throat.
