I freeze in interviews, tips? (Fresno)

I have an interview on Thursday and my stomach is in knots. It has been a long 16 weeks. I have practised answers but they sound stiff. What calms you down?

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

Prepare three stories with a clear beginning, action and result, and adapt them to the questions.
