I have recently had 5 episodes in the last 3 months where all of the sudden I feel like my vision is closing in, my heart races, I can t breath, my thinking is unclear and I feel like I am going to pass out or die. The last incident woke me up at 5 am this morning and lasted 30 minutes (the others only lasted about 5-10 minutes). I am wondering if these are panic attacks and what may have triggered them? The stress in my life has not increased more than usual. Also, if they are panic attacks, will they eventually go away? The only change in my life is that I have reduced the amount of Amitryptyline I am taking at night because my menopausal migraines are becoming less frequent. Is it possible this may have triggered these attacks?
