is it normal to feel awful on adhd meds or does my body have to get used to it?

so far ive tried a few different types of Adderall [off brand since that what my insurance well cover] and ive tried long release Ritalin [off brand] but I even spent money to get Azstarys, but currently I'm trying a fast release Ritalin... but i keep having the same effects with all of them... I get sweaty, I'll have use the rest room a lot and my chest would get tight almost as if im having a panic attack but without the panic I'd just feel all around crappy BUT my mind well be perfect! Id be able to get my work done I wont get distracted im less panicky but my body feels like its going though the ringer...
I'm not sure if this is just something my body has to get used to and the feelings well go away? it doesn't matter what doses im on ive tried 20mg 10mg and now im trying 5mg I still get the same effect
my doc wanted me to try a version that builds up in your system that I have to take daily but I dont want to do that I like the as needed medication Ive had adhd my whole life im in my 30s and I just now started trying meds so I can help focus to get my work done
