Lisdexamfetamine
"Well I've been on many medications throughout my life  for asperger syndrine and ADHD and this particular one has been the most effective, I'd say Vyvanse and Strattera are the best medications for treating ADHD symptoms. So give Vyvanse a shot! Be patient with it too. It takes time finding the right medication. 

I also have low dopamine and the main thing that Vyvanse does is it increases the amount of neurotransmitters in the brain such as dopamine and norepinephrine, so that is a huge plus for me."
