I had sleep apnea. Before I quit drinking, I was stopping breathing 7 times an hour and needed a CPAP device. . A year after I quit, I was down to stopping breathing once every OTHER hour.
I still use the CPAP device because I never store with it and that makes my wife happy. I don’t really need it anymore according to my Dr.
You can do it, you really can. I tried to get quitting to stick so many times. I tried off and on for years until I didn’t have to try any longer.
