<s>[INST] I barely drank any alcohol about 4 hours ago  (two beers and started drinking a little buy of vodka when I started to feel extremely nauseus), but I have been excessively vomiting for the past 3 hours. I am now experiencing chest pain and residual nausea. Have I been drugged? What could cause excessive vomiting when little alcohol has been consumed? [/INST] Mostly it might be related to the food you took in afternoon or just before or during the drink. Also maybe mixing two types of drinks may have caused it if you are not used to it.   Also if you above 40 years of age do consider getting and ekg in the ER, if vomiting or chest pain persist s.  Regards </s>
