Serious situation but mom is on it

My 16 year old has always been the type that gets drowsy in the afternoons and wants to take naps. He sometimes snores, lately he's not been getting quality sleep, but there were not any significant markers to worry about.

Keep in mind, he's a football player, stout muscular kid. He works out every day, does protein shakes, has joined track and field to do power lifting. BUT he's got a thick neck... had his tonsils out as a kid too.

Yesterday though, his 14 year old brother and he came blowing through the front door like they'd just seen Bigfoot!!
"Mom!! Almost crashed the car! Fell asleep and ended up in the opposite ditch!!!"

I listened, life suddenly in slow motion. Both of my sons had eyes like saucers.

Everyone was okay. The car was fine. He did fall asleep at the wheel and his brother had his face in his phone so didn't notice until the car was driving down the ditch.

So, I drove them to school today. I'm making appointments. I'm googling and look into any and every option.

He scared himself and it scared everyone else.

I'm thinking sleep apenea because he's not getting very good sleep and never really has. Is he depressed.. he says he's fine.
A google of teens falling asleep behind the wheel makes me want to take the keys forever... scary shit right there.
