I am also ADD, but I refuse to be medicated all the time. Once I finally got tested at the age or 30 or so (I had no doubt I had ADD), they prescribed various medications and I did try them, but couldn't stand the effects. I've just pretty much gotten used to the fact that I think a little bit differently than most people. I do find that I am much better at problem-solving because of it, though.

Funny story - One of the parts of the testing was where they handed you some black and white blocks, then showed you a picture, then you had to assemble the blocks to match the picture in less than 2 minutes. After about 10 times of repeating this, and doing so successfully every time in roughly 5 seconds each time, I finally told the lady giving me the test that I can solve a Rubik's Cube in less than 2 minutes and that the test was pointless.
