These so called xperts will tell u whatever the book says. I was on coreg and after 3 months had dizziness. It progressed over the next few months. I had a catherization to check for,arrhythmia came,back,normal. Had a ct scan and tilt tabl test and all normal. Went to an Ent and all good. So now I’m weaning off coreg and it’s the second week. I’ve gone 4 days without and had chills and headaches., today was good except having some sob. So I took one and will see what happens. My,dizzy has been better but will see what happens with the sob. Also I’m I’m 5 mg of lisinopril.
