How to get switched from Vyvanse to Adderall?

Is there a reason for you to want to take Adderall? Usually doctors don't like being suggested what drugs to prescribe, especially when it comes to stimulants.

I think if you don't feel like Vyvanse is cutting it for you you should simply be direct with your doctor. Explain what you're feeling and why you think it's best to switch to something else. He may prescribe Adderall or any other stimulant to see if that works better for you.
