I was prescribed Vyvanse today and am excited to attempt to treat my BED. I have a question though and I hope this does not seem crazy or shallow... but I turn 40 on Saturday. My husband has planned a whole day of events which involves food and drinks. Should I hold off on starting my prescription until after the birthday weekend? How does alcohol mix with vyvanse? Not that I will get rip roaring drunk but perhaps consume a few to celebrate the big 4-0!
