Hangover or something else?

In Norway visiting my friends. I drank very heavily with multiple alcohol types on Friday and it’s Sunday now. Threw up three times Friday night, felt bad on Saturday. Now my appetite feels completely ruined, like I’m not hungry. Everything I’ve tried to eat this Sunday I’ve vomited back up in the span of an hour later or so.

Is it normal for a hangover to last this long? Never had effects like this last more than 24 hours.
