When I finally complained to my doctor that I was tired of being tired he referred me to an ENT doctor who did a sleep study and recommended a UPPP and corrected my deviated septum at the same time. No results! Connected with Beth Israel Deaconess sleep clinic....best decision ever made. Throughout the process I learned that I most likely had it during my teenage years. Fast forward, participated in a research study. Learned about affect on short term memory. Yes, it is affected. After treatment began, night sweats, frequent nighttime urination, morning headaches, heavy chest all went away. I am certain that an uncle had the same thing and passed away at a young age. Turns out I have two brothers that also were diagnosed after myself. Love my machine!!!
