I was prescribed 30mg of vyvance. i took it at 12pm and i felt like an insomniac last night. if i stop taking it after one day will i be able to sleep?

Yes: It should be out of your system in 24 hours. In the future, you need to take vyvanse (lisdexamfetamine) first thing in the morning, as it is long lasting and this is why you could not sleep.
