What do you feel after 1 day without Vyvanse?

I don't know if it is just me, but when I miss Vyvanse I feel a lot of undesired symptoms, I feel a lot of anxiety and fear, also tired and asleep.

What about you, do you feel anything after 1 day without Vyvanse?

I didn't try more than 1 day without it, I'm curious to know how long until my body doesn't miss it anymore, does anyone have any idea?
