Sorry, I don't have any hangover remedies to offer. Maybe one - don't drink in the first place (boring advice).
I was drunk once in my life. That was when I was in the German armed forces (the so-called Bundeswehr). Some comrades encouraged me to drink more than I could take (which is ridiculously low amounts of alcohol to begin with). I felt extremely bad (reportedly I've been saying "I don't wanna live any more"), had to vomit several times. Then they dragged me to the bathroom and turned on the shower. That helped a bit (also to clean up the clothes).
Lesson learned ;-)
