I don't puke after i drink. i rarely even get a headache as long as i stick to one brand of liquor with the exception of wine needless to say and don't mix it with any sweet stuff. Bear in mind rum is made from sugar. I don't always abide by these rules,but i stopped puking for the most part a while back. excessive bar mixes will make anyone barf though, so use those sparingly. good night and good luck.
