Will drinking alchol kill intestinal. Worms?

Perhaps, but? There are many kinds of intestinal worms. Generally, worms are cured only by specific medications that target the worm, it's metabolism or in other ways cause it to die. A belly full of alcohol perhaps will kill a worm or two if in contact long enough and in high enough concentration but don't take this as a way to treat them. Get seen, get a proper exam and get proper treatment.
Nah. Tough little buggers. They thrive on hostile environments. It takes a lot more than a belly full of whiskey or ...(fill in your choice of favorite alcoholic beverage) to bump them off. Agree with dr. Profitt; get seen, get checked, get treated-the right way.
