Medication increases anxiety

Hi everyone. I have ADHD and my psychiatrist prescribed me 2x 10mg Adderall IR. Because I have pretty bad health anxiety and taking Adderall makes my body and heart feel very weird I can only take 2.5mg daily. I feel good off of it, but I feel as if it doesn’t last long enough. I was wondering if there are any supplements that could help with focus while I take my Adderall or if anyone has tried a very low does of Vyvanse like 10mg and does that work similar to 2.5mg of Adderall. Thank you!!
