"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."
