I was reading this post and decided to register so I could reply. I've been working myself off of adderall. I'm sure there are plenty of side effects related to how the brain works, but I learned that the adderall was actually covering up poor health and poor diet for years! Things got so bad even with the adderall, that I had to do something. Doctors were making me worse. I finally went to a functional medicine doctor and have been cleaning up my system. I learned what a truely healthy diet actually is. I found out my brain was starving for nutrition as was the rest of my body, allowing all kinds of bad things to take hold. My chronic fatigue included reduced thyroid function (doctors seem to only know diseased vs. healthy and have no idea of the range of function so many of us continue to suffer), adrenal fatigue, and lots of infection from a weakened immune system.
I'm here, a year later much healthier. When I started, I was taking 60mg adderall XR in the morning, 15mg in the afternoon and had added wellbutrin a year before this (another stimulant.) Naturally, I've been working to get off the adderall. I'm now down to like 3 30mg pills which I only take on the days I work out with my trainer. I feel great the days I take them, but not so great on the other days. My doctor retired and I don't really want to go to a new doctor (I'm without insurance now) or spend more money on medication. I'm thinking of breaking down the capsules I have left into multiple capsules. I've even learned that when I eat is important to recovery. Vegetable juicing is awesome for healing too.
I'll make a post later with more details of my story. I just wanted to point out that it is just withdrawl of the amphetamine - it is also the uncovering of the health problems the amphetamines were disguising that make getting off them a journey.
