Alcohol poisoning hypoxic brain damage?

[neurogenesiss]

One time I drank 1/3 of a 1L bottle of whiskey in 30 minutes. I passed out. I remember throwing up and then passing out again. I slept for 8 hour. I read that alcohol poisoning can cause dehydration, leading to low blood pressure and low supply of oxygen to the brain. Also, that alcohol in high doses can slow your breathing, also causing inadequate supply of oxygen to the brain.
Did I suffer alcohol poisoning?
What are the chances that I my brain starved of oxygen while I was passed out?
It’s possible that I suffered some kink of brain damage from this single episode?

No one can answer that. You would need to see a doctor, be evaluated and possibly need an MRI if there were any symptoms .

If there were no symptoms, it means I’m fine, right?

The only way to know would be to see a doctor and maybe an MRI of your brain. Alcohol poisoning is not a joke, and damage that could be caused by lack of oxygen isn't either.

My psychiatrist said I am fine, and a MRI isn’t necessary. She said that given all the details, I didn’t drink enough to cause sedation to the point of hipoventilation. I also didn’t drink enough or long enough to cause severe dehydration. I probably vomited the alcohol remaining is in my stomach and slept (I woke up on my bed, which means I walked there).
Should I trust her or do a MRI anyway?
