I have suffocated myself with my hands around 10 times in the last week, I hold it for around 20 seconds maximum, and every time I do it until i feel dizzy, the dizziness lasts under 5 seconds. My only concern is
brain damage, what is the likely hood of that causing permanent
brain damage. If it did, how severe, and if its irreversible. I did not lose my consciousness, was able to stand immediately after and during it, without stumbling. Only vision got blurry with dizziness for 5 seconds.
