W/vyvanse i eat very little. usually apples/bananas/skim milk/protein supplements. should i take a multivitamin due to restricted calorie intake?

Vyvanse (lisdexamfetamine): Vyvanse (lisdexamfetamine) should have that effect only for few months at the beginning or when doses are increased along time. Most patients recover their appetite in one to three months, or they eat more in the evening. If those are not the cases, maybe vyvanse (lisdexamfetamine) is too high or it is not the best for you. Discuss this with your prescriber and monitor your caloric intake. Multivitamins never hurt.
