New to Adderall: How Do I Know if it's Working?

I noticed it working in the very first day I took it. One of my biggest challenges is emotional regulation. On the same day that I took it, I was triggered at least three times by various things. I found that I was able to pause and reflect and steer myself away from spiraling, which was something I really wasn't able to do before being medicated. I think it's different for everyone. Whatever your biggest challenges are with ADHD, you should see a marked improvement. Ask your doctor how long it should take, but from what I've heard from others and experienced myself it shouldn't be more than a day, maybe two.
