that is interesting theory..yes i can see that, that way life will have a lesser impact on your brain.... in my case (and now i am talking about my experience before stopping ADs), I felt that it happens when i am too tired (which is almost all the time), it is as if my body is shutting down "not essential functions" - i mean compared to breathing, blinking...etc... every few weeks i would have a good day when i have energy, and then everything is easier, from walking to thinking.... and now, it feels like my body is extra tired, after the last few months of horrific withdrawal, plus my sleep is still bad.. so it kind of makes sense that my concentration and memory are so bad...
