Vyvanse is dexamphetamine. I suppose you can say “amphetamines” instead, I imagine the subtleties of the terminology differ quite a bit in different places.
Strattera can help (I mentioned bupropion, another SDNRI). Of course if you try stimulants and don’t respond well, it’s totally fine to just use e.g. Strattera. What I’m advocating against is e.g. “try Strattera first, if it seems to help, don’t bother with stimulants”. (Some places, cultures, or medical systems do have surprisingly strong biases against stimulants!)
