Picture an 4 way intersection.
For me every single car just went about their way all willy nilly like it was nothing.
Occasionally a semi hauling triple trailers flys through grinding every else to a halt when everyone is trying to get through.
There's no order, the lights don't work, and almost no one wants to yield.
The cars were ideas, things I saw, and things I needed to do. The semi is my latest hyper obsession. The non functional traffic lights were my ability to regulate my thoughts.
When I took my meds it was like the lights started working suddenly. At first they were really strict, one car at a time like a highway on ramp. But then things amped down a bit as I got more used to the meds. I even went up to 60mg atomoxetine from 40mg where I started as things ramped too close to chaos again.
I hope that made sense.
