i am allergic to drinks like whiskey,vodka, rum...

i am allergic to drinks like whiskey,vodka,rum,gin.i noticed big mosquito-bite like rashes on my shoulders,knees,thighs,stomach or heels etc every morning when i wake up after consuming any one of these liquors..an avil tablet or a citrizine helps but only for half a day.plus the rashes are itchy and red and would not go until after 48 hours..it is generally after 6-7 HOURS of consumption that this happens...just 1 peg is enough to get me these allergies.however,beer having less percentage of alcohol does not give me such serious allergies.unless i try to have more than 2 bottles. even around my fingers and toes, i get this itchy burning sensation as if there are heat boils inside my skin but there is nothing visible on the hands or feet...just invisible boils maybe..i know i am allergic but there is no one in my family who has alohol-intolerance..i drink very rarely...once in 8 months or even lesser ...just socially with friends..please tell me what to do..would having white rum give me lesser rashes?or any other drink in particular?
