"i was originally on concerta for my add and got extremely depressed and almost suicidal. i then switched to adderall which i took for 4 years without many problems, until i developed a tolerance to it and my dose got so high that i was getting a bunch of side effects. i tried strattera, which i did absolutely nothing and made me really sleepy. then i switched to vyvanse which worked about the same as the adderall but i wasn&#039;t as irritable and didn&#039;t have the same loss of appetite. however, i did start to develop acne, which i didn&#039;t realize until recently was being caused by the vyvanse. i&#039;ve also developed a major dependency, if i don&#039;t take it, i have trouble doing daily tasks and i&#039;m really tired."
