Vyvanse literally SAVED my life, in every way. I couldn't function at home, school, in relationships, ANYTHING. Different medicines work for different people. My two brothers also have severe ADHD but Vyvanse only works for me. In my experience, it wakes my brain up, & calms it down. It helps me to think clearly. Because when I'm not thinking clearly, I literally act like a maniac. If i had to rate Vyvanse on a scale, I would say 10/10, absolutely amazing. But other people might not. My bestfriend also has ADHD, and she takes it and loves it as well. Then again my brothers actually act worse on it, so you never know.
