40 Vivanse for add, don’t eat breakfast or lunch

Patient: I currently take vivanse on 40 milligrams for add, and I’ve been eating a lot less. I don’t really have time in the mornings for breakfast, and I only have some pickles and lays for lunch, because the medication makes me not hungry, so I only really eat dinner. Is this healthy, and if not, any tips?

Symptoms: No appetite
