As to your question, my guess is that this is the alcohol coming out through your pores and is smelling a bit like a toxin at that point. Also, when you drink alcohol you can become dehydrated. Being dehydrated can cause a body odor. My husband has this. Always after he gets off a plane, he has a specific smell due to a bit of hydration he always suffers when flying and other times in which he is dehydrated. I tell him he needs to get something to drink whenever I smell that smell. :>)
So, that sounds like a big bender you must have been on for the night. Hope you are done with the smell and hang over now. good luck
