I take dexedrine (and not adderall) and was just recently diagnosed at 33. BUT..
I don't have to fight to learn. For the first time in my life i have a thought ( " I need to finish my homework. ") i walk over get my homework out and finish it in a single session. Before i would think about doing homework, put it off for hours, finally get frustrated enough with myself that i can force myself to do it, make tea and check my phone, have tea and sit down about an hour later then i had planned do ten minutes of work, lose interest, fight myself, get frustrated, and have to walk away with really only having done 10 minutes of work.
This last example applied to hobbies, work, watching TV, relaxing, to everything. i highly regret waiting but am now quite a bit happier.
