"this particular generic adderall does not work at all (m a20).  i was diagnosed with adhd late in life after thinking i was stupid and shy for many years. i have been. on adderall  20 mgs for approximately six years and it changed my life completely. . i was able to concentrate and earn a degree in early childhood education. for the past three months i have been given this particular generic adderall and i&#039;m now back to square one of not being able to concentrate, can&#039;t speak to my peers on topics that i know like the back of my hand, don&#039;t want to go out, etc, i don&#039;t understand the difference in the different types of generics but i feel cheated out of my life because of my pharmacy."
