Whisky nausea

Whisky nausea, need quick advice

So yesterday evening I drank a bunch of cheap whisky, I usually drink vodka every now n then, but I wanted to try something new, I messed up the dosage and Maybe drank too much a bit too quickly (I’d say around 200ml, not sure tho), the feeling of being drunk on cheap whisky is really different from vodka, its kinda controlled but rough at the same time, anyways (is 75%btw, same as my vodka which Im used to), I’ve been have this werid feeling in my head, it kinda hurt and I don’t think its a hangover cuz its been quite a while, Im also having constant stomach aches and indigestion…I’ve had hangovers before and this is different, almost like my brain cells r popping, its a bit hard to type aswell..blurry..need some advice? What should I do (apart from hydrate ofc) thx
