Happened to me a few days ago after a very drunken evening. I remember towards the end that I felt very queasy but ended up not throwing up (went to the bathroom to try and chunder but nothing came out). I ended up going to bed quite wasted, however I woke up with with the smell of vomit and there seemed to be dried puke on my duvet and pillow.
I also was super super hungover.
Has this ever happened to anyone else?
