I knew with my health issues I had to keep my lungs clear so I took allergy meds, walked in front of my house and picked up sticks in my yard, turned my Cpap up from 10 to 12. When my doctor asked me how I did going through it when I started telling him about my Cpap he stopped me and said let me guess. You modified your Cpap didn’t you (he knows I like to tinker). He laughed and said that was very smart and just shook his head. Lol
