Hi, I was on a flight and after being in the air less than an hour and having had 2 glasses of sparkling wine, I suddenly got incredibly dizzy - I felt waves of dizziness washing over me and felt overheated, then I couldn’t hear or see, I kicked my shoes off as I felt really hot, and what seemed like 10seconds later, the flight attendants and the two passengers next to me were all looking worried at me and asked if I was ok. Then they asked me my name, etc - I then saw my scarf was on the pull down table and asked who took it off, and they said that I was unresponsive and just sitting there staring straight ahead with a glazed look, so they took it off and the flight attendant had gone and got cloths and ice and put them on the back of my neck and wiped my face - I asked if I had passed out and they said no, I was just sitting there - so it had to be at least 10-15 minutes that I was “out of it” - I am scared now - could it have been a stroke?
