Hotel bar

[Miley]

I'm having difficulty understanding (or feeling) this poem, it could be that I'm a dense reader. I wonder if you're not making things more obscure than you need to. I've given my understanding of a few lines below; sorry I couldn't give any more concrete feedback! Thanks for sharing. 

Tempted by the healthy hand Can't read this without thinking of that song "Tempted by the fruit of another" haha, otherwise... ok we are at a hotel bar, the healthy hand is the serving hand? serving alcohol? 
that leads to smooth departure. smooth departure is the feeling of being drunk? Departing from worries etc. 
Contemplations resting at the bottom of 
clairvoyant liquor. I like clairvoyant liquor, the words sound pretty, and I imagine looking into a milky cauldron, or the hazy eyes of a seer. The narrator is drinking and contemplative.
Whether luck has struck its cord-- Here is where I get lost, I'm not sure what this conjecture is, or the role luck is playing? That and the syntax just reads a bit clunky? 
a matter of conjecture.

The walk alone proves
my settlement--
you should've known better.
