I didn't mean to scare you, but I thought you wanted to hear the truth - whatever that may be.
I have respritory depression, which is basically the same thing as sleep apnoea in that you don't get the oxygen you need!
My SATS were dropping as low as 26% at night - which can kill you. It really can.
I was falling asleep all day. I had constant headaches. I couldn't function.
Apart from, as kew says, falling asleep driving (you have to report having sleep apnoea to the dvla) It can in extreme cases lead to strokes, high blood pressure and heart disease. It isn't something to ignore.
It was not my intention to scare you. For a start, I can't possibly tell if it is sleep apnoea. But stopping breathing when you sleep must be checked out urgently.
I now have a bipap and my oxygen levels remain fine overnight. I am alert during the day and my headaches have gone.
There's no need to be scared, but you do need to make an appt with your gp.
