Thanks, that is exactly how I feel. And I got training for taking similar interviews in this industry in the future - something I eventually will have to do because my current position is only until June. I got industry exposure and that is a wonderful thing. It is not my current industry, which is why I care so much.

You are probably right, forgetting one word during a tough interview can happen to everybody - I am probably too quick to attribute it to a Lithium's side effect. It I truly had it as a Lithium side effect, it would have been happening all the time. As it stands, I have more fingers on my hands than the instances of forgetting a word in the past. So I probably should leave Lithium alone.
