"i have been talking vyvanse for just a week. 40mg. the first 3 days i couldn&#039;t sit down. i cleaned my house and my parents. not just cleaned but extra clean, like walls and moving furniture and everything. but now it has faded a little. i noticed right away that when i am doing stuff, its like i really concentrate and try perfection for everything. my appetite has been curved, but i still eat. but no where like i did before. so far i lost 4pds. it&#039;s been almost a week. i don&#039;t get any feeling of jitters, or that i&#039;m taking speed. i feel normal, i just want to do stuff. i&#039;m more social. i always stayed in my home, but now i just want to go out. it&#039;s very nice feeling. i have no problems sleeping either, but i also take it as soon as i wake up"
