Meds dosage strategy

Hey everyone, speaking generally about dosage of any med, what criteria do you/your doctor use to determine you’ve reached the optimum level?

Do you stop increasing once you’ve apparently eliminated acute attacks, or do you continue higher in the hope of reducing overall symptoms?

Or, do you accept a lower dosage with more symptoms to keep the dose down, for example, to minimise side effects?

In my case I eliminated acute attacks at 10mg of Amitriptyline, but found significant further relief of other symptoms at 20mg. I’ve remained there in fear that increasing further would risk greater side effects, though I still have some residual dizziness and the odd episodic deterioration.

Thoughts?
