The big problem with ADHD medication is that basically every patients reacts differently. There is no real general formula. With some patients, even small dose changes can make a vast difference.
Basically all you can do is try a medication/dose combo, observe and record what happens, maybe tune the dose slightly, and talk to the doc again if one medication does not work for you.
I am generally very sensitive against drugs, noise, bad swimming water, ...
So I react way more than others.
Two issues here. It is no problem to just split a pill. I open it up in a good vessel, shake it a bit and eyeball ⅓ of it. No atom science.
And I would like to tell my doctor that I want to increase the dose, if I dilute anyways, I wouldnt need to go that often.
There is a 40mg 100 capsules package, which would last like a year for me!
But at the same time I would like to tell him that 30mg is not a safe dose, he should teach first time patients to open the capsule and dilute themselves. You can easily do that.
But then he might not prescribe me what I need, because some garbage argumentation that it is not safe to split yourself or whatever.
I might just try it, and explain my reasoning. He is kinda nice.
But at the same time I would like to tell him that 30mg is not a safe dose,
Leave it to the medical people what a "safe dose" is. If the capsules have 40mg, they have achieved this value not by just eyeballing, but by amazingly intensive testing.

If you have doubts on or problems with the prescribed dosage, please discuss this with your doctor. It helps if you can give detailed information on the effects it has. I have to admit that I have no first-hand experience with ADHD medication, but I closely followed the struggles of my daughter to find the right medication, dosage, and application method, and it took her quite some trials and changes of medications to find what helps her best.
