Hiya, this is my first post, and was just wondering if anybody else wakes up having a panic attack. I've suffered from anxiety for most of my adult life and have been on sertraline for the last 5 years. My current bad spell has been happening for the last 2 months where I wake up within an hour of falling asleep to my heart pounding and then straight into a panic attack. I have been to the doctors and have been given propanolol and they also did a blood test which showed low iron, so I'm also taking iron tablets. I'm also keeping a diary of them because it seems to be worse within a week and half of my period starting.
