How to prevent nausea during hangovers?

I’m 26 & since drinking (about 18) I’ve had horrendous hangovers which include extreme nausea & usually some vomiting the next day. Sometimes I don’t get the nausea, but when I do it’s unpredictable and ruins my whole day. It doesn’t seem to matter if I drink one thing all night or mix different alcohols – if I have more than 4-5 drinks, I’m hungover and vomiting the next day, never the night of. For example; last night I had only vodka all night (albeit 6 shots) and drank a ton of water/sports drink & ate a ton before, but I was still very nauseous today. A few weeks ago I drank much more and didn’t have water, but didn’t get the nausea the next day.

Most of my friends don’t seem to get nauseous at all when hungover – why is it that I do? How can I make it stop? Remedies?

Thanks!
