Preparing for my first interview in 11 months - what worked for you?

I have an interview on Wednesday and my stomach is in knots. I want to come across as confident and honest. What calms you down?

Arrive early, drink water and take a slow breath before you walk in. It sounds simple but it helps.

Thanks for writing this out. I went through something close to it 11 months ago, and it settled down once I kept a simple log of every call and form.
