The CPAP is not always necessary! If your husband has his natural teeth, he can try a mouth appliance. My 81 year old sister switched to this and is amazed by it. If not, he should talk to his sleep specialist about EPAP, which is simple and non-invasive, about implants, and about other new treatments. After years of neglecting my apnea because there’s no way I would use CPAP, I finally scheduled a sleep study to address it because I learned about these effective alternatives.
