Treating a Variety of Sleep Related Issues 
Dr. Billmann diagnoses and treats a variety of sleep-related issues. While insomnia is the primary focus, his cognitive behavioral therapy programs help patients with:
- Chronic Insomnia – Difficulty falling or staying asleep or having non-restorative sleep on most nights for at least a month
- Circadian rhythm sleep disorders – Disruptions in a person’s circadian rhythm, or a person’s “body clock”. Circadian rhythm disorders may be caused by factors such as shift work, pregnancy, time zone changes, medications and more.
- Hypersomnia – Excessive sleepiness, as evidenced by prolonged sleep, difficulty maintaining an alert awake state during the day or undesired daytime sleep episodes.
- Parasomnias – Disruptive sleep-related disorders that are characterized by undesirable physical or verbal behaviors, such as nightmares, walking or talking during sleep.
