When drunk on alcohol does it vasodilate or constrict your aorta and coronaries? how much does 4 pints dehydrate you?

It depends: People develop tolerance to alcohol and there are big differences in effects based on sex, age, other substances/food used etc. Alcohol generally is considered a vasodilator. I think the question is the wrong one. A better one may be: is my relationship with alcohol a healthy one? Might it be a good idea i ask for some help or find out more about the effects of alcohol on one's health.
