I was on 5 mg of ambien nightly for a couple of months when I started getting heart palps. After undergoing tests
, etc, we read where it could be a side effect of ambien
. By then i had taken it nightly for 5 months. I quit the ambien, and that's when everything came crashing down. Of course there were sleepless nights, but the anxiety attacks, crazy blood pressure and heart rhythm changes, awful generall feelings engulfed me.
