{When taking ADD meds,} I found that there were fewer shiny things going by in my brain but that they were going at slower speeds and so I could actually see them and interact with them rather than just go "What was that?"
I'm unsure if that is very clear to someone that is not taking ADD drugs and I'd like to make it so that it is generally understandable. If you're willing, I'd like to change it as necessary so that I'm understood by the general populace.
