My problem wasn't so much about waking up, but what I did before going to bed; I would roll in bed for hours without getting any sleep, check my phone and think about everything.

I decided to leave my phone outside the bedroom and never taking it (no exceptions) and go to bed regularly at the same time, after a few days by body adapted and I'm having wonderful sleep again, to the point I can remember my dreams again.

All the numbness that I used to have in the mornings is gone, also I don't take any coffee or tea.
