What this practice offers

A CPAP clinic fits the mask, sets the pressure and handles replacements. Ask about a trial of two or three mask styles, the replacement schedule your insurance covers, and what happens if the pressure feels wrong after the first week.

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.
