If you are tired at all during the day, get an at home sleep study as soon as you can. Treatment makes a world of difference.

I wasn't diagnosed until I was older, but I suspect it started mildly in my 20s after a long bout of tonsillitis.

Furthermore, don't take snoring as the only sign of apnea. People assume if you don't snore or struggle then you don't have apnea.

I never snored, I just stopped breathing for whatever reason. I got married and my spouse noticed it. I couldn't believe it.
