Vyvanse? Is it extinct in Houston or is it just me?

I’m prescribed 60/70mg vyvanse a day depending on what’s available and it seems like anything 50+mg is not available ANYWHERE in Houston. Now I can find places with 30mg but of course my insurance only covers 1 vyvanse pill a day and ain’t no way I’m paying $700 for my prescription. Anyone know a pharmacy with 60/70mg available??
