I freeze in interviews, tips? - first time posting

I get tongue-tied when I am asked about my weaknesses. I have read a lot of threads here and could not find my exact situation. I want to come across as confident and honest. 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.

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