"i am a 33 yr old male, i started taking vyvanse yesterday and it is the first medication that i have ever taken for anything really. i was b student in school because i refused to do homework, i couldn&#039;t concentrate enough to motivate myself to do it and i suffered in college for it. now i manage restaurants. i am happy with that choice but lately as pressures from work seemed to increase, i chose to see a psychiatrist to help me complete tasks. i am taking 50mg a day, i usually wait until noon to dose since i work until 1 am most nights. so far, so good, a little jittery but it is new to my system. slight loss of appetite but nothing that concerns me. i am happy with my choice so far."
