No effect from medication

just asking because i’m curious, i was originally on the Xenidate/Xaggitin/Concerta type of methylphenidate (just whichever i could get). i started on 18mg about a year ago then went up to 36mg then 54mg. i was switched from this to 50mg Equasym because of manufacturing issues around August or September and switched from that to 30mg lisdexamphetamine last week.

when i first started Xenidate and every time my dose went up i’d have 1-3 weeks of really severe fatigue, not really able to do much except stay in and sleep. at 18-36mg i had no other effects but at 54mg it helped even my mood out and i felt calmer on it. it still had no effect on any ADHD symptoms other than emotional regulation. when i switched to 50mg Equasym it had no noticeable effect whatsoever. i experimented with taking it at different times of day and stuff to see if i could make it work because i had no access to psychiatry at the time and there just wasn’t a difference at all between taking it and not taking it

i’ve been taking 30mg lisdexamphetamine for the past 3 days. i know this is only the starting dose and not very long but i haven’t noticed a difference so far compared to not taking anything. when i talk to friends with ADHD they say it’s strange to not even experience any side effects, has anyone had similar experiences? did higher doses make a difference? my psychiatrist doesn’t know anything about ADHD (she’s in her 70s and another psychiatrist had to talk her into treating me because there are no consultants on the CMHT currently) so i try to get an idea from others with lived experience where i can
