how long until cpap helps
So, for the question of how long it takes for CPAP therapy to have effect, you should not be asked until you are into this for at leas three month or so. However, use the machine every night, at least 3 to 6 months, until you can feel a difference from how you feel now. Most likely you have had untreated sleep apnea side effects for a long time, and there are residual effects that linger, sleep debt that needs to be recovered.
