I have it, and yes it silently will fuck you up if you don't take care.
I was snoring very loud, waking up more tired than before I sleep, and was falling asleep every time I was in front of my computer working ... I was already affraid of driving.
Sleep apnea:
- fuck your heart
- fuck your mind (bad mood)
- high risk of a stroke and a shit load of other complications
- long term sleep apnea will damage your brain cells due to lack of o2
and much more stuff I can't remember now.
For 3 years I'm using a CPAP unit and DON'T be affraid, it will help you a lot.
