Wanting to try

My doctor has prescribed me 3 different dosages of Adderall IR and XR (these past 2 months) but nothing has worked for me so far, and I’ve been on it all my life but I took a year break from it so I’m just now returning to medications. I was wondering if Concerta would be a decent alternative? I know the chemicals are different so I didn’t know if it would work kinda the same. Experiences???? Vyvanse is way too expensive to be an option anymore.
