Have you considered trialing medication? ADHD medication is among the most effective brain-targeted medication known to medical science. Both methylphenidate and amphetamine-based drugs have a 90% effectiveness rate.
I know that goes for every disease, but the internet likes to paint ADHD medications for ADHD people like it's a literal cure-all.
In regards to stimulant efficacy, I would love to see the effectiveness rate over a time span greater than a few months to a year. I would like to see 10 and 20 year long studies (I understand the difficulties).
Anecdotally, the medications help, but I would consider them to be like a low dosage of painkillers for a burn victim -- better than nothing.
How anyone thought of this and made it actually work is mind boggling.

I imagine, it's since been fixed or the companies in question are no longer producing it.
I find all these ingenious delivery systems (including Vyvanse, Maydays, etc.) to be pure marketing gimmicks.
The approved ADHD medications are highly effective and this has been shown through a great deal of well conducted research both by the companies and by independent researchers.
