How does being on ADHD medication make you feel?

I've been doing titration for over a year now, tried three different medications (Elvanse/Vyvanse, Atomoxitine/Strattera?, Methylphenidate/Concerta) and I don't feel any different.

Honestly, I'm not really sure how I should feel?

So for those of you who take ADHD meds, can you feel them working? What does it feel like when it works?

I'm getting super paronoid that because the medications don't seem to be working that means that I don't have ADHD lmao
