For me, my add has been made much better with aggressive weight training. I started doing "Starting Strength" and transitioned into the Texas method but three pretty heavy workouts a week really helps.
Normally I feel like I see the world through the narrow end of a funnel. When I get done with a big workout, somehow for the next day or so my brain is chilled out and I can concentrate again. After two days or so I start to regress a bit but another bout of lifting resets me.
I only really need medicine during periods of bad health or incredible personal stress now.
Interesting, I've recently started committing to a hard 10-minute workout each day of the week, and it's been helping me focus through my ADD a lot better too. I feel so much more alive.
I've also picked up meditating 10 minutes a day and that's been helping as well, but I don't think as much.
I've got a theory about why it works. Basically you're tiring out parts of your brain when you exercise and activating others. Somehow that regulates the neurotransmitters at the heart of add for a while. If I only lightly exercise, I don't get the same effects. The workout has to be strenuous and I need to feel like I worked both body and mind (finishing that last rep under heavy load takes willpower and concentration).
I bet that HIIT could be as effective as weights for me because the curative part seems to come from exhaustion and exercise of will.
Meditation may or may not be as mentally strenuous, I am not really familiar with it.
