I'm gradually reaching the rather startling conclusion that I should *lower* my doses of Ritalin.
I've very much been "going down the rabbit hole" when it comes to taking these medications. Ritalin does not help me with ADHD hyperfocus, but it can definitely make it worse.
When you don't feel any mental fatigue while you're focusing, you can go down any kind of crazy path you want without stopping to question it.
Fatigue would, at times, help me know when it was time to try something else.
