Two Questions about wine?

Does making g guice into wine remove the juice of its natural healthiness such as vitamen C? And also if I just drank two gles of red wine with an alchol content of 8%, and yes I do feel drunk alittle right now, can I excpect much of a hangover later? (I'm sorry if I have some typos and spelling os, I've never tried typing drunk, its really hard!)
