Hello Doctor, Yesterday I woke up feeling extreme dizziness felt like room was spinning, with nausea, body weakness, and extreme sweating. Sounds like a hangover, funny thing I have not been drinking. Could nt really eat, too nautious. Today I feel a little light headed, was able to eat half a sandwich. This really scared me. All I could do was lie still the whole day with a wet wash cloth on my head. What do you think it might have been?
