Hi, I used to take adderal for ADD when I was in my early 20s.<p>40 mg&#x2F;day is a LOT... who put you on that dose? I was taking 10-20 mg&#x2F;day and it usually left me feeling totally zonked. (I&#x27;m about 200 lbs) Taking 40 mg was a sure-fire way to spend the day grinding my teeth and babbling frantically.<p>I definitely experienced paranoia, and tended to fixate on things outside my sphere of influence, which lead to feelings of helplessness and despair. At the time I thought I was seeing things more clearly.<p>After a while I realized that while adderal was effective at improving performance in rote tasks, it messed pretty severely with abstract reasoning. I ditched it cold turkey one day and never went back. Surprisingly there were no withdrawal effects. After stopping its use, my grades in university level math and computer science improved dramatically.<p>I now believe that psychiatrists are wrong about prescribing adderal for ADD, and that adderal is not a safe or effective long-term treatment. Frankly, I think the whole field is either in denial, or corrupted by financial incentives.<p>Some people will tell you that you need someone to objectively evaluate your mental state, but I don&#x27;t believe such an analysis is truly possible. Best-case, you&#x27;ll get an educated guess and some good advice. Worst-case, someone will try to prescribe you even more drugs. So before you do that, quit taking speed, and exercise regularly. You might be surprised by how much better you feel.
