Maybe I`m off the wall on this one, but curious if anyone else experienced this problem. I had acid reflux, etc for a long time. Doc gave me Aciphex. My heartburn went away after a week but I started getting irregular heartbeats when I eat. At first if felt like a small clump at the bottom of my esophagus and then I started having these heart palpitations, sometimes I get lightheaded. I quit taking Aciphex because I didn`t have this problem before. Even after I quit taking it, I still have this problem after 12 months. I didn`t go back to the doctor because I pay the bill out of pocket, no insurance, and after $3000, I`m supposedly a healthy guy. By the way, I`m going back to a different doctor evenutually.
