Hi, I woke up suddenly in my sleep, feeling dizzy, sweating but not hot, the room temp was 25 degree celcius, that was one hour ago. I never had this symptom before, right now still feeling dizzy, my face is not red, i did have 2 cup of coffee and 2 beers last night and that was about 8 hours ago. I also had quite alot of sea food so i was thinking maybe I had cyanide poisoning from seafood?
