"this is a wonderful medication. i am so happy i switched from adderall. i find the focus and concentration to be awesome. without a doubt it is the cleanest feeling adhd medications on the market. if you have co-morbid anxiety disorders, this is the medicine to go for. i always felt anxious on adderal or ritalin, but the dexedrine is so smooth that i find my anxiety is being helped! i would definitely recommend this to anyone who has adhd, especially when others have caused increased agitation. i believe this is the best adhd medicine on the market."
