If propranolol only helps to reduce the "physical" symptoms of a panic attack, what. symptoms can i still expect to feel?

The Rest: Fear, anxiety, senses of impending dread (though the latter is adrenaline-mediated and should be helped somewhat by the beta blocker propranolol). Also you may still feel a racing heart - it depends on your individual response to the drug.

I agree: You should try to slowly reduce the dosage and see how you react. Dosage monitoring is the best way to determine how well you'll be once you either severely reduce or eliminate the drug from your daily intake.
