is there a recommendation for ADHD, insomnia, anxiety?

"My daughter is wondering if she can get off some of her other meds."

I don't have ADHD but insomnia and anxiety have been my two companions through most of my twenties lol I've had success with smoking or vaping the purest indica flower or oil you can find. Indicas are renowned for their mellowing, relaxing high and it has literally trans formed my sleep. And I haven't had a panic attack in 6 months
