2g, I live with a dh who is the poster child for "look, shiny object!" He is not on ADHD meds, but has found a career where linear time is not of paramount importance and a wife who keeps his edges organized.  
Likewise, dd was on ADHD meds at one point, off for a couple of years, and is now on a lower dose of a different med (because she has learned many, many coping skills she did not have as a young elementary schooler, but is in a much more rigorous/rigid learning situation).  She doesn't take her meds on the weekend for the most part (though I don't like letting it go over long weekends or vacations because it seems to make the subsequent Monday go weirdly for some reason).
To medicate or not to medicate is an individual choice, dependent upon the child, the educational situation, the timing, and a thousand other things.  I would neither opt in nor opt out because of "in general"s and "a lot of kids"s. You have to look at your child, specifically, and her situation, specifically, and determine the benefit (or not).  And then make your decision based strictly on her, and the heck with what other people do or say.
Easier said than done, because everybody and their cousin's cat will second guess you, but at some point, quite a bit of of parenting comes down to doing what seems like the best idea, and hang the rest of the world.
