I have been taking Vyvanse for about 3 months. I have noticed a significant change in my productivity level at work (my boss was about to put me on a suspension for being so scattered and forgetful of directions etc.) But I do feel as though I lose that around 5pm. I don’t want to do much of anything when I come home from work, including cook or eat a meal.
It has been suggested to me by my psychiatrist that I take the medication slightly later in the morning instead of 6:30am with my other daily meds.
Good luck with finding what works for your symptoms!
