About The Insomnia Clinic

The Insomnia Clinic has a unique capacity to help solve the problem of poor sleep without medications. We do this by bringing together cutting-edge sleep science, proven sleep system retraining methods, advanced sleep discovery technology, and expert-trained clinicians, coaches, and trainers.

We are a group of healthcare, research, and education professionals who believe that natural sleep is essential for optimal health and maximum quality of life. We believe there is a solution to every sleep problem and are passionate about helping people find their personal sleep solution. We believe that healthy sleep is possible for everyone. We also believe that healthy sleep is almost always possible without the use of medication.

Insomnia is a big problem. An estimated 30% of adults struggle with insomnia symptoms or an insomnia disorder that negatively affects their health or quality of life. We mainly serve two types of insomnia sufferers. The first type is individuals who are looking to solve an insomnia problem and are unwilling to take a medication. The second type is individuals who are already taking sleep medications and need help achieving healthy sleep without them.

The science on solving the problem of poor sleep without medication reveals that there are many pathways back to better sleep. This is why the services of The Insomnia Clinic are based on a stepped-care model. In this model there are levels of care, with each level having a greater degree of intervention and support.

Not everyone needs to see a healthcare provider in order to restore healthy, natural sleep. While some patients will benefit from interventions as simple as a self-help book or short educational workshop, others will need one-on-one clinical evaluation and treatment. This is why we provide a full spectrum of educational and clinical services to help you achieve better sleep quickly and in the simplest and most affordable way possible.

Sleep medications like Ambien, Lunesta, Belsomra, temazepam, trazodone, amitriptyline, benzodiazepines, and others have a critical role in our health care system. They help millions of Americans sleep better and, through better sleep, live healthier, happier lives. However, long-term use of sleep medications is associated with meaningful risk of potentially dangerous side effects as well as psychological and/or physical dependence.

Additionally, for a majority of individuals, sleep medications are unnecessary. There is now solid research evidence showing that nonmedication treatments called cognitive-behavioral therapy for insomnia (CBT-I), like those we offer through The Insomnia Clinic, are as effective as sleep medications and are beneficial for as many as 90% of insomnia sufferers.

The Insomnia Clinic evolved from the personal experiences of our founder, Dr. Robert N. Glidewell, who struggled with poor sleep for the first three decades of his life. His personal struggles with insomnia, his training as a psychologist and sleep expert, and his personal and professional experience within our healthcare system has shaped everything we do and everything we believe about the problem of poor sleep.
