A side note: I don't have ADHD, but I'm also a "flopper" when I read. When I was 16--way back before it was fashionable!--I learned to knit in Germany using the Continental method (off the right hand instead of the left, as is the norm in the US) and taught myself to do it without looking. Throughout school, whenever I had reading to do, I picked up my knitting. The constant subtle motion kept me FAR more focused than I would have been if I had stuck to the reading alone.
This glorious habit kept me nailed to my chair through an undergraduate degree in English and 7 tortuorous years of grad school for the same! I don't know if it would work for everyone with a bad case of "the fidgets," but it works like a charm for me.
