"I have just started using Vyvanse a couple days ago. Even though I haven't been on it for very long, I already notice some differences in my everyday life. Almost everything has changed for the greater good. The only bad thing I have to pick on is that I have experienced a multitude of side effects such as headaches, rapid heart beats, and dizziness. Other than that, I like Vyvanse so far. My opinion in the future may or may not change, but most likely not. The effects of Vyvanse are pretty immediate, for me at least. It has also come to my attention that some people don't notice any change sometimes."
