If you try adderall it will be very different, focalin is dexmethylphenidate which means it’s the right handed isomer of ritalin. In my experience, which admittedly was brief, ritalin was more similar to modafinil in terms of just being awake. Adderall usually also gives a bit of euphoria and just sense of enjoyment in whatever you’re doing (but that’s been variable for me lately since the shit made by Lannett hasn’t really been doing that). But either way i think with treating adhd it’s kinda similar to psychedelics in how set and setting affect what happens. If you take it and set yourself up to focus on something productive, it’ll help, but if you just take it and see where it goes idk you’ll spend 6 hours arguing on the internet about some stupid shit and/or jerking off
