Limbo

[gedankespieler]

can't decide if your love's become poison or soma
it's typical tobacco teamed with cold coffee
crutches on which we navigate our particle of the cosmos
warm light beaming through the shutters
it's morning and we've sinned again

This seems like a collection of sentences rather than a poem; it's not sonorous. I'd advise paying more attention to the rhythm and sound of the words.

e.g. in this alteration -
"it's typical tobacco teamed with cold coffee,
crutches we use to traverse our cosmic particle"
- the "-ic" sounds similar to the "-ee" and the "-le" is close to "-ld"; and "particle of the cosmos" is to stuttery between "particle" and "cosmos", which jars with the previous line because the ending syllables there are all stressed pretty much evenly. "navigate" was a little jarring because it is composed of three short syllables; "traverse" continues the alliteration and consists of two longer syllables, making it easier to read in the context. Also, "on which we" is a little clunky because these words alliterate despite being irrelevant to the meaning of the poem.

Punctuation always helps as well, for example:

can't decide if your love's become poison or soma.
it's typical tobacco teamed with cold coffee,
crutches on which we navigate our particle of the cosmos.
warm light beaming through the shutters -
it's morning and we've sinned again

Oh, and I'd replace "beaming" with "beams". The "-s" carries through to "shutters", "it's" and then to "sinned", making the last couple of lines flow better.

I suppose you get the gist.

Aside from the technical details, I think you'd do well to expand on the theme a little more. It's quite ambiguous as it stands, and doesn't seem to drive a point home, rather, it seems there are a few points that haven't been fleshed out. I guess the general advice is don't stop until you've fully realised your mental image / concept.
