Oh yes, the ER would have known what you had. I caught e-coli in France a few years back, got sick the day before we came home. Try to imagine being as sick as you were and being on a plane for about 9-10 hours. Fortunately the plane was only 1/3 full and I had a whole row to myself and the bathroom never had a waiting line. I still had diarrhea 2 weeks later and the doc put me on antibiotics and it finally cleared up.
I can't imagine being on a plane that long being that ill. Thank goodness the plane was only a third full!
Have just been reading up on e-coli. I think what got me through it was Pedialyte. At least I was getting some electrolytes in my system. Oh, I used a store brand. Probably Gatoraide would have done the same thing.
Thanks for the education!
