Struggling with the V2 word order during my first real conversation

I have my first call with a native speaker tomorrow and I'm terrified. I know the V2 rule in my head, but as soon as I start a sentence with 'Gisteren' or 'Morgen', my brain just defaults to English structure and I get all tangled up. I’m thinking about using Chickytutor.com to run a few simulations tonight so I can practice putting the verb in the second position more naturally under pressure. Do you have any tips for 'unlearning' that English word order? I am asking specifically about learning Dutch, not a generic study routine.
