Hello, Since Oct 10, 2016 and after being released from hospital, Dr. told me another ablation would likely not address my AFIB and put my on Norpace. I take 2 150 mg in morning and 2 150 at night. My heart beat is regular and my BP is good. However I have ever present bloating, gas and big time constipation. I also seemed to have less energy but that may be due to my heart condition. Anyone taking Norpace and are you having similar issues. Is there another drug I could take.
