I recently started to take adderall at 28 years of age. My doctor told me that they found out that at least 1/3 of the adderall will still be working the next day, and 1/3 of that the day after. And the 1/3 was the at least number. So he told me to take it intermittently and not every day. I do really like that stuff, although I have had 1 or 2 bad experiences, for the most part it makes me feel normal and relaxed. Also, my doctor told me my diet will greatly affect how the adderall works in my body. And that really rang true to me. I usually eat pretty lean, so 10mg, or even 5mg is enough for an effective dose for me. I tried to get provigil from the same doctor and he couldn't even believe I would ask for it, said it was too expensive to prescribe to someone like me.
