Are you overwhelmed, anxious, and burned out? Are you having difficulties falling asleep, staying asleep, waking up too early, or even all of the above?

If you've been lying awake night after night, exhausted but unable to sleep, you already know that willpower and sleep hygiene tips aren't enough. Chronic insomnia has a way of becoming self-sustaining, the more you try to fix it, the worse it gets. CBT-I breaks that cycle by targeting the thoughts and behaviors that are keeping your sleep broken, without medication and without an indefinite course of treatment. Most of my clients with insomnia are high-functioning adults who have been managing poor sleep for months or years, often alongside anxiety or depression. They've tried everything they can think of on their own. What they haven't tried is a structured, evidence-based approach designed specifically for the way insomnia actually works. CBT-I is the gold-standard, first-line tre ...

Hello, I’m Leon Yang (楊里祥), a licensed counseling psychologist based in Taipei, Taiwan. I work with adults struggling with sleep difficulties — lying awake unable to fall asleep, waking repeatedly through the night, rising too early, or never feeling rested.

My approach is grounded in Cognitive Behavioral Therapy for Insomnia (CBT-I), the first-line treatment for chronic insomnia recommended by international sleep guidelines — more effective and durable than sleep medications long-term. CBT-I targets the real engines of chronic insomnia: weakened sleep drive, disrupted circadian rhythm, conditioned arousal in the b ...
