The mindfulness variety. I got started with it as a part of my explorations of ACT: (see http://thehappinesstrap.com/)
"How long/frequently?"
Most days, once or twice a day for about 1/2 hour at a time.
"What benefits have you experienced?"
I feel I am more aware of things in general and I do feel I struggle less with negative thoughts and emotions as I am learning to take a step back from them and see that they are just the output of an active mind.
The idea is more that you can't really directly control your thoughts and emotions but you can learn to see them as just thoughts and emotions and that gives you some room to move towards what you want instead of struggling with your thoughts and emotions by trying to change them or get rid of them; which just tends to increase the negative thoughts and emotions. I don't know the efficacy for ADD specifically.
