I drank 4% alcohol at my university and I lost consciousness really briefly but I had to be carried to my room and put in recovery position. I was by one of the girls carrying me that looked like a body. I'm really concerned about my health. What do you suggest that I do?
I'm a bit confused as to why you are telling us what the alcohol percentage was rather than how much you drank. If you only drank a small amount, then passing out would be unusual and it could possibly be a sign that something is wrong, I guess? If you drank pints and pints, then yes, passing out is one of the things which happens when you get blind drunk. Since you didn't die at the time, you will be fine from that one occurrence. If you do it regularly, then yes, there are health implications.
It has no health consequences since you already didn't die before you even woke up (which would have been unlucky, but does happen). But you asked what people suggested - isn't not doing it again kinda obvious?
