I started taking it in my late 30s for ADD and it was life changing. Over time though it was making me super angry so I stopped taking it. I now focus on sleep and exercise but my career really accelerated while I was taking it.
After that 10, I tried amphetamine which blew holes in my persistent brain fog. I went on Adderall and (as we've often heard) it changed my life.
I'm not advocating you change a regimen that is obviously working for you. I'm just adding another possible plotline to that same story.
