After a couple of hours (I slept through most of it), they got me off the stretcher and onto a chair and handed me ginger ale and saltines (which I checked for kashrut.) The ginger ale was regular, but when they remembered I was diabetic, they gave me diet. And then I got dressed and Jonathan took me home by cab.
(And all the time I was chugging that drink down last night - 4 liters drunk a cup at a time at 15 minute intervals - I kept thinking about Harry forcefeeding Dumbledore that potion. It works EXTREMELY well.)
