Perhaps someone saved it, I saw a link on here to an article that said it is mostly expelled through your breath.

Becomes the CO2 you breathe out as its burned is my understanding.

As well as H2O, as odd as it sounds it all seems to be exhaled.

SciShow on YouTube mentioned this in one of their videos.

The products of combustion are always co2 and h2o.

Well, not exactly. The products of perfect combustion of hydrocarbon compounds are CO2 and H20. You can't fuse or split atoms with fire.

Your body metabolizes it like how your body metabolizes food.

I think it is expelled in urine and feces.

It is exhaled through your mouth and nose, actually. source

A small bit does come out through urine though, but not feces if my understanding is correct.

Metabolizes in to mostly water. So basically energy and pee.

Something like 90% is carbon that leaves via breathing out, with another ~6% being secreted through sweat and various oils, with the last little bit being pee and poo. Interestingly enough, the reverse is true for most plants: 92% of the mass of a tree comes from carbon dioxide from the atmosphere.
