Wow! So thankful to hear about this problem of anxiety upon waking! I have been experiencing this for months off and on ever since I had Covid 2 years ago. Even before I am fully awake my heart is pounding. I have to get up and take a Xanax then go back to bed until things calm down. Low dose does not make me sleepy thankfully. My psychiatrist says this is "normal" for his patients with anxiety issues. I had back surgery over a year ago and am still suffering with lots of pain except when I am lying down. I know that has caused lots of stress for me physically and mentally. Thanks for sharing. This has been helpful.
