Interview nerves, what actually helps? - what worked for you?

It has been 3 months since my last interview and I feel rusty. I am in Raleigh, in case local advice matters. I have practised answers but they sound stiff. How do you prepare answers?

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

Ask about the first ninety days. It shows you are thinking about the work.
