"i have been in treatment for add for 15 years. as a result i have tried and used several of the standard drugs used for treatment including adderall, ritalin, dexadrine, and wellbutrin.  about 3 years ago i began using strattera. i was made aware that the medicine did not affect the dopamine levels but should still help prolong my attention time. since then i have found this to be true. however, the difficulty is since the impact it is seemingly subtle. it&#039;s very difficult to gauge the effectiveness and to determine the proper dosage.  after 2 years, my doctor and i are still tweeking this aspect.  overall, strattera has worked to allow me to still have something for my family left after a long day work."
