"정말 신물이 납니다."

Translation: I am really disgusted.

[rkirsling]

Evidently 신물 is not Sino-Korean, but literally 신 물 (sour water), and thus means "bile".

[Jeong-JinL]

I'm feeling a bit bilious thinking about it myself.

[PimWendall]

Can anyone explain the 납니다? Is it 나다?

[kf_b]

Yes, it is 나다.

[oee16]

Lit. translation:
"My bile is actually churning up." ?
