Granted, I have not had as many as most the posters here, for
me, a lot is 5 a day, but, those 5 scare me so badly I am paralyzed with fright
. I have had the Echo, holter monitor, and all blood work, and they are glowing. EVERYTHING is perfect, so, I can only chalk mine up to extreme anxiety. I DO have panic/anxiety attacks, and when I am in "anxious mode" I do notice the buggers acting up more. Also, eating and drinking lots of water at once will sometimes trigger them.
