It's mostly sleep deprivation though. I graduated with a 3.7 from a top 5 school in CS after I was treated. My apnea was SEVERE before treatment: 30 apneas per hour.

I doubt I had any brain damage, though my study only recorded a min SpO2 of 90%.

Before CPAP, How many times do you actually remember waking up in middle of night?

[Hydraulix989]

Once or twice. Usually you don't consciously wake up in a way that allows you to remember it whenever you have an apnea, you just go into a lighter and less restorative sleep stage.

From someone else with apnea: absolutely none at all.

I didn't have to use CPAP to treat it though, so other people's experiences might be different.

How did you treat it?

[ctolsen]

I use a mouth guard, it turned out to be sufficient.
