Everyone is different, of course, but after 10 years it would be reasonable to assume that your brain was well-adapted to many of the effects of the Adderall and that you were taking a reasonable therapeutic dosage with a proper, healthy dosing schedule.

On the other hand, those who abuse Adderall for the initial euphoric and energetic properties with sporadic dosing schemes are likely to experience unpleasant withdrawal as those effects disappear.

I can't imagine a withdrawal for amphetamine outside the come-down from a multi-day binge. The come-down lasts a day or two. Maybe a week of fogginess if you hit it fear-and-loathing hard.

If you're taking amphetamine at such a rate that you would call it a "withdrawal", then you might want to consider the possibility that you were abusing amphetamine.

It's common to double-dose on the weekend whether for a productivity spree or recreation (they're usually one in the same) even if you haven't taken a pill in months. You just have to pay a day or two penalty and you're good to go.
