Hi. I too, just took my first dose of Lexapro earlier today (Tuesday), and had the exact same symptoms you describe. It was just like a Panic Attack. I have never heard of this happening with just one pill - but a couple of years ago I took one dose of Neurontin and had the dry heaves within 20 minutes.... needless to say, I never took another one.

I think I might stick with the Lexipro, but cut them in half, to make them 5mgs instead.... lessen the side effects.
