Counter productive: Vyvanse (lisdexamfetamine) is a stimulant. 5 htp is converted to seratonin and has sedating properties that mya counter the stimulating effect of vyvanse (lisdexamfetamine).. If you are using 5 htp to help you sleep, speak to your doctor about other approaches to sleep initiation.
