Hangover tips NEEDED

So I had a fun NYE but I’m paying for it this morning. I’m realizing I’m not 21 anymore and I can’t drink and not be hungover anymore so I’m pretty new to the hangover thing. Basically, I’ve been throwing up and having diarrhea (sorry) for 3 1/2 hours and I think I’ve gotten everything out but I still feel sick and nauseous. My fiancé keeps telling me I need to drink water and eat something but the thought makes me want to barf all over again. What can be done at this point? I’m really over feeling so sick.
