I freeze in interviews, tips?

I have an interview on Friday and my stomach is in knots. It has been a long 15 weeks. I want to come across as confident and honest. Any questions to ask at the end?

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.

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