I stopped taking Adderall years ago because I had so many negative side effects. Headaches being one of them. Iirc there’s some sort of “syndrome” that people on Adderall can get if it doesn’t agree with them, and they get all kinds of nasty symptoms. There’s testing you can do to find out what medications will and won’t work with your specific body chemistry, I highly recommend you ask your doctor about it. When I did it they immediately told me Adderall was a no-go. I take jornay now, which doesn’t have a generic so it’s more expensive but I don’t ever feel sick. Even if I drink caffeine, which I rarely do because I just don’t feel like I need it anymore.
I’ve also heard good things about azstarys and Concerta.
No, thankfully it was something specific to Adderall and most of the effects went away when I was switched to different medication. This was a few years ago so it’s hard to remember exactly what was said but I got the impression that it was not very common or well understood. They just knew that Adderall disagreed with some people, and I was one of the unlucky ones.
