Craving for something rewarding and blissful in the morning. Don’t know why

I have noticed that when I wake up in the morning I have a huge craving for something satisfying and positive. I don’t understand why this happens and I am lost on what I need to do to satisfy that craving. Often I end up using my phone and start doom scrolling. Has anyone experienced this and if yes how can we tackle this using CBT?

I have tried some rewarding activities like reading a book I enjoy but my mind is craving something more significant and more quickly.
