what is the science behind it? how can you get symptoms of sickness without actually being sick? why does your body respond that way?

>how can you get symptoms of sickness without actually being sick
By “sickness” do you mean infected with some virus or bacteria, like having a flu? Not every “sickness” requires being infected with something. If you don’t drink enough water and get dehydrated, you get the symptoms of that (headache etc) and I’d say that *is* a form of “being sick”. If you ingest poison, that can make you sick too.
BTW, a hangover is those two things I just described! It’s the physical after-effects of drinking too much of a toxic substance, plus very likely being dehydrated at the same time.
>why does your body respond that way
Because you’re literally poisoning it. Your liver does a good job of not letting the alcohol itself build up, but what it turns the alcohol into is also somewhat toxic. Between damage by the alcohol itself and its byproducts, you can’t drink too much poison and get off completely scott-free.
