Propranolol
"I must really have a problem. I take it for singing at church. But need a much higher dose than most I see on here. When I am just singing with the Praise Team I take 60 mg, but when I sing a solo I take 100 mg to feel no symptoms of heart palpitations, feelign like my throat is going to close with no notes coming out. And im 5'3 115 lbs female...started with 10mg and kept having to increase dosage until I felt symptoms gone during a performance.  Seriously dont know what I would do without this medication!!"
