"i have all the time a panic attacks daily. i&#039;ve been prescribed different ssris over the last 10 years and they haven&#039;t helped. also, i&#039;ve been taking xanax x3 times a day for the last 3 years. i just started taking propranolol and i&#039;ve noticed it works wonders. i don&#039;t get chest pains and the racing heat beat. i&#039;ve reduced my xanax use to only once a day which is huge for me. i haven&#039;t experienced any negative side effects except for mild fatigue at the end of the day (i take it in the morning when i wake up)."
