I was wondering if there a many drivers that have sleep apnea? If so, do the CPAC machines help or are they not usable in this type of work? My husband did all the purchasing and delivering of our product when we had our own family business. It got to where he couldn't stay awake long enough to make the drives alone. It wasn't until after we had to close our business we found out it was sleep apnea. He's doing better and is considering going back to some form of driving if the CPAC will help enough for him to be able to drive again. I was trying to find out if others have been able to return to driving and if this will keep him from getting his DOT health card. Thank you for any help. New Team
