I need help

I got drunk last night and didn’t eat before going to bed at 2:30 and today after waking up I’ve had a terrible headache and nausea. Well I kept the nausea at bay for a while but threw up while working a side gig. I then came home where I am now and I was still too nauseous to eat and when I did I threw up. I had so little in my stomach that nothing came up except stomach stuff. I have been hydrating. It’s 3:16 pm where I am. I haven’t eaten enough since the afternoon yesterday. When I threw up the second time it actually kinda hurt my mid section. Not really my chest but stomach and all. I just need advice please
