I don't normally have issues with insomnia. A few nights a year, I will sleep particularly badly, but it's an outlier. Sometimes it's due to stress or being too warm at night, and sometimes there's no clear reason.
Unfortunately, in the past couple weeks I'm developing a pattern where I wake up in the middle of the night (between 3-5; I fall asleep around 11:30 or midnight) and am unable to go back to sleep. When I wake up in the middle of the night, I feel wide awake, no yawning or tiredness, as if I'm ready to start the day...except I'm not.
How do you get out of a bad sleep pattern?
