High Blood Pressure
"Switched from atenolol to Coreg CR to avoid the wall I would hit when doing cardio-exercise. I felt less of the wall from the cardiac side, but seemed to not breath as easily while doing cardio and while at rest. Felt like I had to force myself to take deep breaths on Coreg CR. Never had that happen with atenolol. Also, lost some libido on Coreg CR which wasn&#039;t an issue with atenolol. Switched back to atenolol and these issues all went away. "
