I am a wine drinker. Have drunk wine without a problem for maybe 15 years.   For  the past 18 months I have been having strange symptoms the Docs have been unable to explain despite many tests.  It s usually some hours after drinking, I  feel very hot and sweaty, get head rushes which sometimes leave me for a few seconds with humming in both ears.  I sometimes, but not always, get some palpitations.   I have kept a diary and seems this happens when I have either drunk more than usual night before or maybe I have had a little more over a period of a few days.   The head rushes do not seem to fit in with other comments on this site, but other symptoms ring true.  It is odd that it doe snot often happen quickly, but more likely the next day.  I have had heart, blood pressure and balance tests, hormone check (had prostate removed several years ago) and even had a brain scan.   Anyone get these head rushes?
