Not a chemist or even a frequent caffeine user either, but from my experience you can't reduce the effect of something you take to its active principle.

For me, the same whisky has very noticeable differences in the effect and after-effect depending on how it's served / mixed.

I always assumed the line about water "opening up" whiskey was just about flavor and personal preference, but I just did a bit of looking around and apparently it might also get you drunker faster. Diluting vodka 1:1 with water apparently speeds up absorption quite a bit, so there's something physical happening, at leas tin the stomach.
