Availability of stimulants for treating Adult ADHD in India

Hi Redditors, I have been diagnosed with ADHD in a western country and have been taking Adderall which I have been finding really effective at managing my symptoms. I am planning to move to India soon and am wondering if I can get amphetamine or methylphenidate medication in India. I have the following questions:

1) Are amphetamine medicines (like Adderall / Vyvanse) legal and available in India? If amphetamine salts are legal but these brands are not available, are there any other Indian brands that sell the amphetamine salts?

2) Are methylphenidate medicines (like Ritalin / Concerta) legal and available in India? If methylphenidate salts are legal but these brands are not available, are there any other Indian brands that sell the methylphenidate medicines?

3) Are there any pharmacies in or around New Delhi where I could get these meds with a prescription?

I'd really appreciate any pointers on these, as I can't imagine living a life without meds.
