Hello~I see this was posted on the 17th, I hope you are better. If this happens again, I would go to the ER as soon as possible, I did a search on it just now, and it said the patient should not sleep, and should be watched carefully for about 24 hours. Don't mess around with this, it is better to be safe than sorry. What you described did sound like a form of alcohol poisoning.
God bless.
