Lisdexamfetamine
"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't as irritable and didn't have the same loss of appetite. However, I did start to develop acne, which I didn't realize until recently was being caused by the Vyvanse. I've also developed a major dependency, if I don't take it, I have trouble doing daily tasks and I'm really tired."
