Vyvanse Export Question

So I’m debating on importing my generic vyvanse with me. I can functions without it, but I’m not the most attentive (brain fog and zone out sucks) and that makes me question how I’ll manage public transit being, not to mention being from a rural area in general. I have a letter from my doctor already, and if I decide to, I plan to bring 12 30mg capsules (just started back on it after a few years of trying to self manage)

However, I’m an avid coffee drinker and there may be a day there I skip it to have coffee at a planned cafe without decaf or if I’m having a good day from trip adrenaline and excitement. My doctor is also one to encourage taking when I need it, but feeling free to back off if I don’t for a day.

I know I need an export form to accommodate this, but how exactly do you fill out a quantity in cases where you’re not sure what that is yet? I doubt this is uncommon as being a healthcare worker, I know many medications such as narcotics are labeled “as needed for X”, thus are taken at irregular quantity and would encounter this same scenario.
