I've been taking addrerall since before it was prescribed to me. I abused it horribly for a while there, staying up 2 or 3 nights in a row. I also drank a bit and smoked pot almost daily.
Now, I have left the drinking and smoking and I am actually prescribed adderall XR. 30 mg in the morning. My 110lbs, male 5'6", has actually increased to 130lbs, which is more toward normal, good health.
I was concerned about dependency one or twice. I was an alcoholic at one point before ever taking this drug and I did not want that to happen again. So I stopped taking it for a few weeks.. and I just felt like a did before.. i would come home from work utterly drained and fatigued. I felt like it wasn't normal but I couldn't get past it. I just wanted to lay down. Stare at a wall for a while.
Adderall has helped me live a normal life, Gain wait, helped me get off my ass, and actually focus once I'm off of my ass. And whence I'm off my ass I still feel normal.. I can make a choice to lay back down or move forward.. Where as before I had no choice.
Look, if your kids start twitching and pulling their hair, losing weight, etc. then adderall is apparently not for them. If adderall makes you feel strange, abnormal, or whatever, consult your doctor or neurologist.
