Is there a specific amount of water that needs to be drunk to re-hydrate after drinking a shot of vodka?

So, for example, if I drink 1.5 oz of 80 proof vodka (and I'm not sure if different vodkas would dehydrate one's body differently), is there a specific amount of water in ounces to drink to bring the body back to pre-vodka shot levels?

Would different hard alcohols change that number?

Your brain regulates the amount of water via your kidneys. Once you start drinking alcohol you interfere with these signals, basically giving your kidneys the command to "flush". So it is not a matter of water/alcohol, as any water you will drink whilst this function is not working properly will also be flushed out.
