YMMV, but “withdrawal” has never been more than a minor annoyance, even after years at relatively high dosage. Tired for a few days, a little bit lacking in motivation, definitely more difficult to concentrate.

The concentration part is usually the hardest, but is not necessarily worse than before the drugs, you just forgot why you went on them to begin with or how bad your ability to focus really was.

I will say, it can take some time to adapt to that lack of ability to focus though, as your coping mechanisms before you took medication are a bit atrophied due to no longer needing them.

The physical withdrawals themself really aren’t problematic though.

My main point of comparison for Adderall withdrawal would be caffeine withdrawal. I don't have experiences with other dependencies.

"Cold turkey" caffeine withdrawal was much more severe than Adderall withdrawal for me. Probably twice as bad. In both cases, I felt extremely fatigued. However, severe caffeine withdrawal went beyond "fatigue" and really made me feel like total shit.

Everybody is different but I believe this is consistent with what most people report.

Of course, there is no real reason to go "cold turkey" and quit suddenly. For both substances can just taper your dosage steadily down to 0mg over a week or two and you should be fine.
