As it turns out, after a sleep measuremement

that where up to 5 breath stops is normal (per hour), I have 66
I snore at 68dB (like a loud telephone)
sleep too light and often wake myself, out of breath or cause of own snoring noise
have (at lowest) only 70% blood/oxygen saturation

which is super heavy on the body/arteries (like running a marathon), which then may/be cause of acid reflux issues and overweight (metabolism troubles). So I need a cpap machine (Continuous Positive Airway Pressure)
