I've had a tough couple of years with pretty debilitating heartburn. I had lots of testing done and didn't respond to ppi's which caused me to have a lot of anxiety.
Throughout this time I've been using zopiclone (http://www.drugs.com/cons/zopiclone.html) which is a sleeping pill. At my worst: anxiety and a lot of pain/discomfort, knowing that I could at least sleep at night was vital.
Then, for other health reasons, I went off of my sleeping pill.
I've had a huge improvement in my symptoms. They aren't gone entirely but they have had a very big change for the better.
I looked up side effects and discovered that heartburn is one of the rarer side effects, so I guess I'm one of the unlucky ones.
I wanted to post this just in case anyone else on the list is having the same reaction to this drug.
Best to everyone,
