What non-prescription therapy??
What you hear about these drugs can be scary, one maybe should remember most will talk about bad side effects but ont the good ones.
There is not one chemical compound that I'm am aware of that does not include 'long term, irreversable brain damage' in its list of contraindications in the PDF.
I base my admittedly empirical conclusions upon years of documenting and investigating unattended deaths...including suicides, and years of running a muni lockup...intake and monitoring of arrestees. Then there are the many acquantences and friends who, through the years, have had experiences related to Ritalin and other compounds used on their children, and the long term effects and results of that therapy.
I'm always curious; I ask questions. I've not seen or heard of a productive consequence of drug therapy. Not once...except in short term circumstances...which, unavoidably, went south, in time. Reputed successes are, as far as my prejudices will allow, to be had DESPITE the use of the drugs.
