This review of insomnia counseling at the Bright Village Mental Health Clinic in Suncheon is helpful.

I've been having trouble sleeping lately. If I fall asleep early, I fall asleep around 4 a.m., and if it gets worse, I fall asleep around 6 or 7 a.m. It's really hard because I barely manage to wake up in the morning and feel sleep-deprived all day.

Also watch videos on YouTube that help you sleep

I'm taking sleep supplements, but there's no improvement.

But I happened to see this review while browsing and it was helpful.

I only thought about things like sleep clinics, but it seems you can go to a psychiatrist for insomnia too. I'm going to go after seeing this review.
