It is very doubtful that this is
simplySimply sleep dehydration. Much more likely that you are having an allergic reaction to alcohol or a particular component of specific alcoholic drinks, called mast cell degranulation. Thus you may experience this phenomenon only in response to certain alcoholic drinks or classes of alcoholic drinks, for example to gin or vodka but not to bourbon or beer or scotch.
You may want to begin a trial and observation of the effects on your skin, of a variety of drinks. You may have to cut way back or even stop drinking alcohol. Here is a citation for an article that points out that alcohol is a common cause of allergic reactions and asthma: Allergic and asthmatic reactions to alcoholic drinks: a significant problem in the community by Dr Hassan Vally in Clinical and Experimental Allergy, 2007, volume 38, pages 1-3.
Good luck.
