Has anyone gone quiet at work after starting stimulants and then worried people think you are cold?

Worrying that colleagues now read you as cold after going quieter on a stimulant is a social question sitting on top of a clinical one, and the two are easy to mix together. ADHD medicines are used to reduce impulsivity and hyperactivity as well as inattention, so a person who used to fill silences, joke constantly, or jump in may suddenly look reserved in the same workplace. That can be symptom change rather than becoming an unfriendly person. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.
