Can keep drinking after the initial drunkenness wears off?

I have discovered something quite peculiar about my drinking, and I’m not sure whether this has any basis in science. Say, for example, I drink a bottle of wine (a daily commitment) — this will get me positively squiffy, but not enough to completely impair any vital forces. However, once this has worn off, I am able to drink scotch after scotch (or any spirit, really) with no discernible feeling of inebriation.

Anybody else like this?
