I'm filipino and I drink occasionally.  Last night I had one mixed drink and a sip of champagne. Right before I went to bed I started getting itchu on the lower portion of my back and on my stomach.  When i woke up, the parts that itchy were beet red and were still itchy like crazy.  This is the third time it happened.  I don't drink beer and wine.  I usually just go for lighter drinks.  The first time this happened I drank 2 mix drinks and the second time I only drank 1 smirnoff. But after doing a little research..I am still confused.  I would very much like it if someone would just please clarify what is going on. Is it allergy?or what?... Thankz so much in advance.
