Saturday night I had some drinks with my friends and overdid it. I threw up a few times and went to sleep for a few hours. The next morning I went home with what felt like a bad hangover. I didnt eat much real food because I couldn't stomach it. The next day I still had a severe headache, naseau, and weakness. It is now day three and I do not feel better but worse. Severe nausea even throughout sleep, headache, its hard to keep my eyes open without squinting. Should i be worried?
