Going to NIMHANS from Hyderabad for Adult ADHD Diagnosis-Need Advice!

I'm 21/F planning to go to NIMHANS from Hyderabad to get diagnosed for adult ADHD. For those who have been through the process, how long should I prepare to stay there? Are there any specific doctors you’d recommend? What kind of questions do they ask during the assessment?

Also, in Hyderabad, I’ve come across doctors who don’t really believe in adult ADHD - are there similar experiences at NIMHANS? Lastly, for medication, do I have to keep traveling back every time for adjustments, or is there a way to manage it remotely? Any insights would be really helpful!
