I love when one sentence can have more than one meaning. Like in "Fireworks" by the Tragically Hip, 'isn't it amazing, we can do anything' could mean 'wow, isn't it amazing we can actually get anything done' or 'isn't life amazing, we can do anything'. Like, I think in context of the song it probably means the former, but I like to think both meanings were intended.
Anyways, do you mean to say 'at the time drunkeness is so much more fun' or 'at the time that's a depressing statement but not while drunk'?
