You can't test yourself for ADHD by taking amphetamines because they have profound effects on everyone - there's a reason why stimulants are some of the most popular recreational drugs. They can make everyone feel smarter, more productive, like you're on top of the world, especially at recreational doses.

When it comes to therapeutic doses for treating ADHD, the effects of the medication should be very subtle, you shouldn't "feel it working" like you've just taken that pill from Limitless. It can produce some euphoria or other recreational effects initially but they're supposed to disappear within a couple of days or weeks, otherwise your dosage is considered to be too high.
