Why do I wake up with a dry mouth, or a dry, scratchy throat?
This may occur if you have inadequate humidification. You may, in this case, also experience mouth-venting (air escaping out of the mouth during therapy). Adding or increasing heated humidification should help to resolve these issues. If increasing humidification does not resolve the mouth-venting, an option would be to add and wear a chinstrap. If these options do not resolve the issue, you should consult your physician.
