I know there is a lot of questions out there about this but I have not found what i need to know. I just got diagnosed with Sleep Apnea and got to get the CPAP machine. I am getting it hopefully next week. I am fixing to go to School and got to get my DOT physical done. Do I need to wait to get the physical and go to school so my CPAP has enough percentages or can i go in and let them know I just getting the machine. I am in the mild area of sleep apnea not moderate or severe.
