"i have take 25mg twice a day or once a day with good relief. twice a day is better. as soon as i stop it i get slight panic, but i also feel like i&#039;m not able to concentrate when people are talking. it&#039;s a strange feeling and then i get pain in my left ribs, under my arms and left upper back. then i wonder if i&#039;m going to faint or have a heart attack. it&#039;s a constant roller-coaster of high and low adrenaline. a small dose of beta blocker worked well for anxiety, but when you are sick, you need a little adrenaline to combat inflammation. it&#039;s an awful balancing act."
