When you're having a hangover from drinking too much alcohol it's gonna feel like you're about to die or you're gonna wish you were dead so that the hangover would be over.
But dying of a hangover is very unlikely.
That is unless you have drank so much alcohol that it lead to alcohol poisoning.
If you've drank enough alcohol that lead to alcohol poisoning and didn't get or don't get medical attention soon enough then yes you could die of alcohol poisoning.
However from a simple hangover it's unlikely that you're gonna die.
But if you do have a hangover from drinking alcohol then that is a sign that you're drinking too much alcohol and need to stop drinking so much.
I had a birthday party when I was 21 which was around 20 years ago now and I got drunk and the next morning I had a terrible hangover.
That hangover made me think I was dying and I wet my pants, wet my bed etc.
But I came out of it but that swore me off of getting drunk again.
I still drink alcohol now and then but not enough to get me drunk because those hangovers do not feel good.
