Allergy to Alcohol

Dear Sir,
  whenever i take in alcohol, i get quite severe reactions to my skin the next day.It gets very sensitive, itchy and it also develops rashes.Is this a sign that i'm allergic to alcohol?Or is this just a temporary reaction?Is there any way i could prevent this from hapenning whenever i drink alcohol?I'm a male, of asian descent.

I to have a strange reaction to alcohol.  After just one beer I get very bright red on my face and the rest of my body.  I also get uncomfortably hot and have a little difficulty breathing.  I can also feel my heart beating very fast.  I know these reactions sound serious, but i can drink a fair amount.  There have been times where I have consumed 5-6 beers in a couple of hours. I am half caucasion and half japanese, 6 feet 2 inches tall and weigh 230 pounds.  Please tell me whats going on. I like to drinf, but these reactions make it difficult during large social occasions
