I don't normally eat Macdonalds but was out with my wife and we needed something quick to eat so shot into one.
I had a Big Mac and Coke.
I was feeling fine and not particularly anxious.
Half an hour after eating I was feeling terribly anxious and nervous - almost trembling.
I drink a tin of Coke off and on and that doesn't normally bother me but the combination of Macdonalds and Coke really set me off. I'm presuming the burger has something in it which combined with the caffeine in the Coke set my anxiety off big time.
Now, a couple of hours later I feel pretty calm again so it must've been the meal.
