Hours used to disappear on me. On meds I can actually tell when the afternoon is passing. Is that a thing?

Noticing the afternoon passing, instead of losing hours, is something some people report after starting ADHD medication. It can feel like a real change, but it is not a labelled side effect with a proven clock mechanism, and it does not happen to everyone. ADHD is associated with difficulties in time estimation and time management, and clinical writing often describes hours disappearing during inattention. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.

I used to look up and it would be dark and I had no idea where the afternoon went. On meds I can actually feel 2pm turning into 3pm, which sounds small but it freaked me out a bit at first. Like the day had edges again. I do not know if that is attention or just me not falling into a tab hole for three hours. I mentioned it at a check-in because I was not sure if it was a good sign. This is only what happened to me, not a thing I would expect other people to get.
