I've had luck at big box store pharmacies (Kroger, Albertsons/Safeway) getting name brand Vyvanse, generic Vyvanse, and generic Adderall without issue here in the PNW. But, yes, some places like Walgreens or CVS seem to struggle.
Currently on Vyvanse, now generic, with generic Adderall as midday booster. Luckily I've been okay so far, but I'm susceptible. I've tried many different medications and this combination works the best without ruining my personality. I'm not sure what's going on with the shortages, but I really hope that shit gets under control. Both for my own security, and for everyone else affected or potentially affected by the shortages.
