Quick question concerta timing when travelling

Hi everyone, Today I have a flight that will last a total of 15 hours, from 6pm to 9am at my final destination. How should I manage my Concerta in this case?

I usually take it exactly 8am daily , but today, since I don’t like sleeping on planes, I decided to take it later. Does that make sense, and could it be a good strategy? I’m thinking about taking it around lunchtime. The main reason I’m taking the medication today is that my ADHD is more on the inattentive side, and I’ve had several issues at airports because of it.

And about tomorrow: since I probably won’t sleep much, I’m considering not taking it. Does it sounds ok ?
