Hi Hamie, I had those same symptoms in response to my GERD. Was taking Tagamet and I still sat up at night with a racing heart. I started taking Protonix and the symptoms slowly disappeared, but I also changed my diet, exercised, slept in better positions, didn't smoke or drink, etc. Now that the Protonix has helped my tissues heal, I will get off it. Allow about
three months for the healing to take place. OTC medications weren't strong enough for me. I have a dread of doctors and medication too, but in this case, the PPI helped to get me out of that crisis.
