I would like to let you know that typical starting dosages of dextroamphetamine are usually in the 2.5–15mg/day range, so taking 20mg and 40mg could have way overshot your therapeutic window. Taking too much will end up not helping. > I'm also not honestly that surprised that it didn't work so well, given how genetic ADHD is It's not necessarily just that ADHD is genetic as much as it is that ADHD is pathological. It affects your whole brain. Sometimes stimulants really do help, because dopamine and/or norepinephrine can absolutely be possible culprits for entire brain dysfunction, but if you happen to have another root cause for the disorder then they might not particularly help. Still, you can't necessarily rule it out just by taking 20mg and then 40mg; it may be possible that a lower dose could still help you.

That's weird... I was given the remains of a prescription which only had 20, 30 and 40 pills, nothing any lower. Would taking too much also have no effect? It feels like it should have too much effect, however that would manifest. Having a quick look at wikipedia, the source of all correct knowledge, it looks like 50mg of lisdexamfetamine dimesylate (elvanse used in oral capsules) is roughly equivalent to 20mg of dextroamphetamine sulfate or 15mg of free base dextroamphetamine, which is backed up by its citation at medicines.org.uk, so 20 lis would be like 6 dex I meant the genetic stuff because the person that gave them to me was close family, and I suspect another close family member has it too, so I'd guess it would present and potentially be helped in similar ways between us, as well as having similar side effects

  You are right, Vyvanse/Elvanse comes in 20,30,40mg. Dextroamphetamine has a different dosage.
