There is also Strattera which is not a stim med. It Increases norepinephrine (NRI) stimulant-like action but lasts all day. Not a controlled substance. No direct dopamine effect so may be better tolerated. However, it Takes 2 to 4 weeks for maximum effects. Must be taken 7 days a week. So you got to give it time to take effect (unlike the instant effect of the stim meds). And it doesn't work for all.
My son is just trying 21cremedies.com ADHD tranquility formula. I can't tell you if it works or not yet since we pretty much just got it. But something for you to look at and decide for yourself. I'm sure others have comments about similar products.
