Ive been on daily beta blockers for a long time, like maybe 30 years, but i would still freak out in stressful situations like being called to the boss's office or even just paying my bills. I totally had to deal with my issues and get t wrapped around me like a blanket in my head before i stopped getting that horrible sinking feeling. But the beta blocker does help with my heart rate. I say pick your battles. If something can help you, why not give yourself that advantage? Really - what do you gain by holding yourself back? Maybe that isnt your issue, but it surely was mine.
