Oh yeah and I have trouble falling asleep so that ' s also one of the reasons why I hope Strattera will work . I also take bupropion . Since they ' re both round the clock meds . I ' ve read a lot of people in here say that their stimulants don ' t work when they haven ' t slept well , and I haven ' t slept well in 15 years now . I recently had 2 weeks where I slep well on Strattera . That ' s unsual for me . I also wonder if that ' s why Ritalin didn ' t work for me , although I heard it ' s common that Ritalin might not work but amphetamines work and the other way around as well . So far I haven ' t noticed any effect on concentration or stopping the 154 thoughts in my head . I ' ve only taken it a month and am only at about 50 % of the final dose so I hope it might come , or else I ' m also willing to add a stimulant .
