I don't have ADD or ADHD but I get very easily distracted and let my mind wander a lot - especially when reading. Like injaga, I can read two pages without understanding it because my mind was somewhere else - or read the same sentence 50 times before I give up cos I can't concentrate.

So I'm just throwing this out there; what about meditation? That's a great way to learn how to concentrate for anyone I think. I use a method where I count to 4 on my in-breath, then hold for 4 seconds, then count to 4 on the out-breath, then hold for 4 seconds etc. and the only thing I have to keep focused on is " 1.. 2.. 3.. 4" so as soon as my mind slips, I can go right back to "2.. 3... 4..".

But that's not really a quick-fix solution for when you really need it, it's more of a way to learn how to be more disciplined when your mind starts to wander and learn how to notice that it is starting to wander.

Worth a try anyway I suppose. x.X
