Say I have a big fuck off exam in a month and no time to study for it. Say I could theoretically come into possession of ADHD meds without having ADHD. Say I might have used them before exams in the past for a while now, but never for more than a week without breaks and always in dosages they give to hyperactive preschoolers. Would taking a more adequate amount, say 10-30mg of Dex for a month straight fuck me up in any serious way? Also, share your experience.
