Would vomiting help clear liquor from system?

Why hurt yourself?: Alcohol (etoh) empties rapidly from the stomach. Alcohol dehydrogenase in the stomach lining contributes to etoh metabolism. Etoh can not be stored by the body & obligatory oxidation takes place predominantly in the liver. 1 gram etoh gives 7 empty calories that provide only energy with no nutritional value. Poor diet (protein-calorie, choline, folate (folic acid) deficiency) contributes to liver toxicity.

No: It will only clear alcohol that is in the stomach. Alcohol that is in the blood will only clear through normal metabolic pathways. Drinking coffee, taking a cold shower and any other "traditional" methods of sobering up are not effective. The only thing that works is time.
