"i was diagnosed with adhd when i was a kid. i&#039;ve tried all sorts of medications, (two type of adderall and i don&#039;t even remember what else). around two years ago, my doctor decided to switch me to vyvanse. it is effective, i won&#039;t lie, but the side effects make it less than desirable. i am a 17 year old on a 7 year old&#039;s dosage and it still causes me to have mood swings, become irritable and antisocial, and kills my appetite. if i happen to be stressed out, on my period, and on vyvanse on the same time (both tantrums and objects will be thrown). i&#039;ve taken to using it on an as needed basis. it&#039;s not as effective this way, and my doctor doesn&#039;t like it, but at least i can balance academics and a social life this way."
