I read the book the first week of January. It's not really the knowledge that I've taken from the book, it's gone deeper than that. I think I'm just a different person now. I often find myself acting in ways that I never would have before, without thinking about it. It doesn't occur to me until after that I did something different. These ways of acting are what people would call normal, but for people with ADD it's a huge difference.
I think it was that the book told me what was missing, and the mushrooms allowed me to experience that missing thing. Now having experienced it, it's not missing anymore, so all the associated problems are either gone or much, much less than they were before.
