Genetically bad hangovers (help)

I (20f) never had a bad relationship w alcohol but starting less than a year ago I’ve had the most excruciating sometimes 48 hour hangovers. The nausea has gotten so bad I have to take anxiety meds to stop myself from panicking after waking up from a night of 2+ beers. Thought Reddit would be the place to go if anyone has any tips on what to take before or after to calm this down a bit.
