What this practice offers
Insomnia is usually treated with cognitive behavioural therapy for insomnia rather than a sleeping tablet. A clinic that offers CBT-I will ask you to keep a sleep diary for one to two weeks before the first session.
Treatment tolerance decides outcomes more than the device does. A mask that leaks, a pressure that feels wrong, or an appliance that moves the jaw too far will all end with the patient giving up, so follow-up matters as much as the initial prescription.
