"If I would be able to drink, I would drink three glasses of wine tonight."

Translation: Dacă aș putea să beau, aș bea trei pahare de vin în seara asta.

Why is "diseară" not acceptable for this evening?

This is an awkward construction in English. "If I would be able to drink" should simply be "If I were able to drink," using the past subjunctive, not the conditional.
