Switched from Concerta to Vyvanse after 6 months — my honest comparison (32F, inattentive)

Six months on Concerta 54mg, three months now on Vyvanse 40mg, and since I compulsively compared them in my notes app anyway, might as well post it. Concerta: extremely reliable mornings. Desk-work focus was genuinely better. But 3pm arrived like a cliff, and I basically didn't eat between 8am and 8pm. Vyvanse: no cliff, more of a slow dimmer switch. Mood is noticeably better — I stopped snapping at people around hour 8. Appetite still reduced but dinner exists again. Neither: fixed my gift for losing keys, sadly. One Canadian logistics note — generic methylphenidate sailed through my insurance, Vyvanse needed prior auth paperwork and 8 business days. Plan the gap. The thing I can't settle: is "smoother" a real pharmacological property of lisdexamfetamine or did I just want the new thing to feel different? Curious what the clinical take is. 32F, inattentive, Ontario, for the demographic spreadsheet.
