ADHD
"I am fifteen years old and started taking Vyvanse 30 mg dose in October.  I moved to 50mg and am now at 70mg.  At the lower dose I noticed definite improvement in my attention span and work ethic.  On the 70mg I feel anxious, depressed, and I have headaches constantly.  I feel like isolating myself socially from everyone else and am extremely moody.  I do not recommend more than 50mg of this medication to anyone."
