<s>[INST] Last night, with no warning, suddenly I became very dizzy, ran to vomit and had profuse sweating.  So, much so that my hair was dripping wet.  Never had anything like that happen.  Seven of us ate the same dinner, and no one else got sick. It was so unexpected. [/INST] Hello!My name is Dr. Aida and I am glad to attend you on Healthcaremagic!Your symptoms are suggestive of an inner ear disorder. Have you had and flue like symptoms lately? What about any head trauma?If the episode repeats, I  would recommend consulting with an ENT specialist and performing labyrinthine tests to investigate for an inner ear disorder. Hope you will find this answer helpful!Best regards! </s>
