I’ve started some new ADHD medication. I’ve been taking Xaggitin (methylphenidate) for a little while, but while I’ve had some net positive experiences with it, I’ve felt the need to try another medication: Vyvanse (lisdexamfetamine dimesylate). Both are stimulants, which might seem strange — surely the last thing someone with ADHD needs is a stimulant! — which increase levels of neurotransmitters dopamine and norepinephrine in the brain. These neurotransmitters play important roles in your ability to pay attention, think and stay motivated.
