Adderall vs Adderall XR Please help?

I have been taking Adderall XR for probably 8 or 9 years if not longer, my new psychiatrist made a mistake and wrote me a prescription for the regular Adderall and I didn't catch it until I got the meds home and realized that they were pills and not capsules and the pharmacy says they won't take it back because its a controlled substance so I'm stuck with regular Adderall for a whole month. I normally take two 30 mg Adderall XR in the morning but how should I take the regular Adderall? there 30mg also just not XR?
