Any tips and advice?

I’m off to Korea and Japan in two weeks, and found out today that my permit application to bring my vyvanse with me was rejected cause my doctor didn’t wrote “personal use” in my travel letter and they wanted more information.

Sadly, I cannot reapply as I’m due to arrive on the 17th of August and applications need to be sent two weeks prior arrival. I was wondering if I should stop taking my vyvanse a couple of days before leaving, or should I take it up until the day I leave?

Usually if I forget to take it, I feel very sleepy and struggle a bit with my emotional regulation (I’m more prone to my autistic meltdowns without it) but I have never gone more than two days without it.
