Note, Concerta should last about 8 hours while the Vyvannse could go 10 to 12 hours. Also
Concerta is a Methylphenidate, while Vyvannse is an
Adderall based med and is stronger. You might want to try the Vyvannse again, but increase the dose slower. Typically tiredness is not a side effect of stim meds, unless you are over dosed and then you can feel kind of stoned.
Hopefully, this helps a bit. Please ask if you need more info.
