I freeze in interviews, tips? - 13 weeks in

I have an interview on Monday and my stomach is in knots. There are 8 people counting on me, so I am trying to be careful. 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 last year, and it settled down once I kept a simple log of every call and form.
