40mg Vyvanse

  1. I'm taking 40mg of Vyvanse tomorrow (2x 20mg) to study for a test and do some readings for my classes. What time should I take these assuming I still want to get to bed?
  2. I would say a good 15/16 hours before you want to sleep. Vyvanse is fucking amazing for studying and it's time released for about 12 hours a pill (20mg). The way Vyvanse works is by having your bodies enzymes break the substance down at a natural rate, instead of chemically binding the pills with fillers that take longer. So theoretically 40mg of Vyvanse would take 24 hours to be completely gone, but you should be good with about 15 hours.

    Good luck on your tests bro hope this helps.
