"i&#039;m a 30 year old male and switched from dexedrine to strattera about two years ago. for the first two months i thought it was a terrible decision because of the horrible side effects and talked to my doctor a couple of times about switching back to a stimulant. he told me that even though it says it can take up to a month to start working, in his experience, it took most patients 2-3 months to see the benefits. i&#039;m glad i stuck with it. after four months all side effects we&#039;re completely gone and it works better than any stimulant type i&#039;ve been prescribed. the problem is you do have to get through a horrible period of 1-3 months (10 weeks for me) before the nausea, fatigue, ed and insane sweating are gone. this drug takes time to work!!!"
