NAC: During a hangover, the body is fighting to regain equilibrium in several ways. Alcohol depletes the body's water, electrolytes and vitamins, so part of the hangover is dehydration, electrolyte imbalance and vitamin deficiency. Drinking water and electrolyte solutions along With Vitamin B supplements can help. Alcohol also causes liver toxicity which can be counteracted by NAC which detoxifies.

NO: N-acetyl-cysteine is a precursor to cysteine, and crosses the brain-blood barrier with eventual participation in glutathione which is involved in free radical control centrally in brain. NAC also lowers homocysteine levels. There does not appear to be any direct utility in alcohol metabolism, or benefits for hangover.
