"strattera is a wonderful adhd medication if you know how it works for you. for me it takes a solid 8 weeks before the full effect of the medication kicks in to full potential. when it does. i have a superb memory through paying attention. my dr. increased it from 40mg when it worked well but not well enough. to 80mg. then i had to restart the 8 weeks. like the 40mg,  i started noticing a difference in 5 weeks. after 6th week it&#039;s a perfect mix. superb focus that seems to get better week after week. i&#039;m glad i gave the statterra a chance."
