ADHD
"I am 44 years old and was recently diagnosed as ADD.  I am a successful professional that always had to work a little harder to achieve results due to my lack of concentration and tendency toward distractions.  I started taking Vyvanse, and have to admit I felt like Superwoman for about a week and ranted and raved about how much I was getting done without the jittery feeling most stimulants provide.  But then all in one day, I crashed.  I started getting extremely agitated.  I then would get so angry I would cry hysterically.  I quit taking the medication and within a few days my mood and attitude have leveled off.  Although, I have suffered from extreme vertigo and exhaustion since I have been off this medicine. I was on 30mg."
