I have been having random myoclonic jerks during the day, usually during the morning or at night, but sometimes in the middle of the day when I am completely awake. I have panic disorder, and sometimes I panic until the attack ends with a myoclonic jerk. I get a strange feeling in my eyes and they black out for a second, and my upper body twitches, but I am still conscious when it happens. Could Prozac be causing this?
