A stimulant used to treat B.
E.D. and A.D.H.D. that can last for up to
14 hours. When taken in higher doses can cause
euphoria, extreme focus, alertness, energy/insomnia, and increase/decrease in anxiety and confidence. Can cause the feeling of 'butterfly's' in the stomach and other parts of the lower body. For some people, it can cause the need to be organized and neat (I'm typing this on
100 mg of Vyvanse). In comparison to another commonly abused amphetamine stimulant, Adderall, the ups and downs of the drug
may not be so distinct/sudden.
