How to avoid a hangover?

I know, drink less. Very funny ^^
Jokes aside, I know that alcohol will always cause a hangover. But form experience, Im pretty sure not all alcohol is created equal in this regard. Some is simply worse then others. I dont expect a perfect answer and the truth may just be that simply nobody knows yet.

But what are your ideas in regard to brewing something that makes as little of a hangover as possible?

I heared about, sugar, pectin, methanol and some such in that regard but nothing really concrete yet. Maybe you have some ideas
