"i started off on 20mg and it did not work very well. i was very angry and still very distracted. although i felt like that was the first time i&#039;ve ever been actually able to focus on daily activities. things peaked my interest more resulting in more productive energy. due to my short temper when i started, my doctor prescribed me to ritalin and that was thee worst experience of my life. after that, we tried strattera which was even worse. i&#039;d get sick to my stomach and just feel so drugged up. after a few different dosages she prescribed 30mg of vyvanse. i&#039;ve never felt so productive and aware. i havent ever realized before this, how many impulsive decisions i make without thinking about the effects. vyvanse has made me more self aware."
