i am 21 and I have been reading on adderall quite a bit over the last 6 months and learned a fair amount the reason i did this was because a long time a ago when i 16 i had taken adderall and it helped me overcome many of my social and work, school related issues this was a major help in my life because the fact i have a dyslexia so it is very hard for me to start focusing and stay focused in everything. This normally had lead me to give up on work, and schoolwork which take a big effect on my grades even with the help of my school aids my question is this is what i understand right where adderall or another drug could possible help me fix my inability to focus and should i talk to my doctor about treatment or do have another solution to my problem

Hi My daughter takes adderall for her ADD. She is 25 years old and only began taking the drug 2 or 3 years ago. Although her doctor recommended that she take it everyday, she only takes it when she goes to school (college), if she thinks she needs it. The last time she took her capsule was Monday of this week. She will be taking a drug test because of work, but doesn t want her new place of employment to know she takes adderall. How long will it take for the Adderall to be completely out of her system and not show up in her blood work? Thanks
