Original uncertainty examples I am currently using a cpap machine and still finding that I am tired and don’t get a good sleep at night, is there any other treatments to use in conjunction with the cpap machine treatment? ~ Are the adjuncts with CPAP (example: a-flex/c-flex/EPR) useful in the treatment and compliance with therapy?
