Hey I am worried about my sister! She is on Vyvanse
right now at thiry mgs but does NOT take it daily. Her husband takes twenty mgs of Adderall daily, and sometimes she will take an adderall instead of a vyvanse. Is this safe?? I don't think she is taking them at the same time but, is it safe for her to take an adderall on occasion? She claims the adderall gives her more energy than the vyvanse so she takes it when she has a night that she is working late and so on.
