I was never diagnosed in service with OSA. I weigh 220 and I am 6′ tall. I am rated at 70% for PTSD and the meds I take add to the OSA. I had my personal Dr. and the Psychiatrist I see both write letters to support that the meds I take add to and cause the OSA. My Dr filled out the DBQ and sent it in as well. I had a failed sleep study results sent in with my claim. I also have documentation I sent it that back up the fact that OSA is tied to PTSD and is aggravated by PTSD. Then sleeping with the prescribed CPAP machine adds to the PTSD. Just curious if anyone has ever won this claim? I am going to appeal but wanted to get any advise here first if someone has any to share.. not sure if there is anyone who has gone this route before and won?
