Propranolol lowered my heart rate but did not help with the feelings of anxiety, so I stopped taking it. I learned to control my anxiety through meditation, and have not had panic attacks since I got out of rehab in April! I used to have debilitating panic attacks several times a week, I was on benzos for them for a while, but started abusing those along with my DOC so I knew I couldn't take them anymore. I now am able to curb my anxiety before it starts. Good luck to you!
