Horrible hangovers…

I’m losing my mind, and I need to know if anyone else experiences this.

Nights when I go out drinking with my friends, I noticed that the night of partying and before bed I’ll be having the buzzed feeling, but otherwise I’m fine and functional and I don’t feel any sort of sickness in my stomach where I would need to puke right away like my friend does. my friend pukes every night whenever she drinks too much (without purging) but I will go to sleep feeling fine and wake up and puke all day the next day until about 4 PM and it’s absolutely horrific because I’m not able to hold down anything and I feel sicker than she’s ever felt during a night of been drinking. I don’t like to make myself vomit with my fingers I think if I’m that sick my body should just do it for me…

Does anyone else experience these delayed-response hangovers? Why is that? Is there a medical reason for this? Why can’t I juke puke the night of like a normal person?
