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

It has been 8 months since my last interview and I feel rusty. I do not usually post, so bear with me. I have practised answers but they sound stiff. Any questions to ask at the end?

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

I record myself on my phone and listen back. The second try is always better than the first.
