Your brain becomes used to Adderall telling it to release dopamine and norephinephrine, and subsequently won't do it anymore without being told. It's the price you pay for getting dependent on Adderall. If you were to go off of it for a long time, eventually your brain might go back to normal. I've had the same issue since going on Adderall for my ADD last year. Before I was on it, I was able to be at least somewhat productive without it, although still not enough to keep my life together. But since going on it, on the days i don't take it, I get nothing done, cause now my brain won't function without it. It's the price I pay, because, ultimately, I can't keep a job without the adderall. it's either be mediocre all the time (off the meds), or have it be one extreme to the other while on them. I choose the latter, since I was never able to keep a job until the adderall. I only take it when at work, so work is the only time I'm productive. But that keeps a roof over my head.
My sister has the same problem. Try to find someone to help regulate your meds if not daily how about weekly? I kept my sisters pills and she just stopped by daily (we live a block away) for her meds. If that doesn't work maybe you can get a weeks supply at a time and leave the others with someone who won't give them to you no matter what.
I did some numbers in my head and asked a few questions in the mean time. As it happens to be My mom has told me the time in which it takes to for me to use my persription is about 1 week. Soo. If I was to stop doing Adderall once and for good, would my depression subside?
