I have adhd too, I get the same feelings you describe. If you'd like to test something out on yourself, get some ephedra, something time released, like lipo-drene, and see how it effects you. WHen I take ephedra, I get very calm, very focused, my mind seems "clear" and im able to better concentrate. As opposed to normal people, who bounce of the walls and shit like theyre on speed. If ephedra mellows you out, you prolly have it.
