Why can't you just say. Szedulsz?
Note that Hungarians often ask questions in the negative which might be asked directly in the positive form in English. It can be a form of politeness.
That would mean "do you feel dizzy?", which is basically asking the same thing, but with a different connotation, both in English and in Hungarian.
Aren't you fizzy? (Said to the toddlers spinning in circles and giggling madly)
