I had mine in December 2001. My GERD caused asthma-like symptons. I never really felt heartburn even though I would wake up in the middle of the night, from time to time, choking on acid that had made it all the way up the esophagus to my lungs. So far, none of these symptoms have returned. But, I do now suffer from esophageal spams. No one knows for sure what causes these spasm or if they are related to the wrap. They are no fun as they mimic heart attack symptoms. My GERD was very bad so I had no choice as none of the medications controlled it. But, would I do it again if it can be proven that it causes my current esophageal spasms? Probably not!
