"i see a lot of mixed reviews on this. it&#039;s obvious this drug is extremely helpful on some and on others its completely ineffective, and can even do harm. my suggestion is to try it out for a month. if you don&#039;t feel the effects of it, try it for another month and if you still don&#039;t then switch to another drug. if you start feeling agitated by it, get off it immediately. for me strattera has worked wonders. i am 18 years of age, and have noticed the effects after my 4th week of taking it. my mind feels clearer, and i feel more motivated to focus on things i would usually find boring. the effects are reflected in my act score: my score has gone up a whole 6 points since first taking it. i wholeheartedly recommend strattera to anyone with add."
