2 years ago I have been taking adderall xr 2 capsules=40mgs, but didn't take it everyday. this year i switched to adderall IR 20 mg taken two capsules a day everyday. My insurance didn't cover my adderall xr this year so thats why i switched. Then a month ago my insurance decides that they can cover my adderall xr again, but once i got to go back to the xr adderall it didn't work the same as it did before. Before I was able to focus and study better and have good energy, now its just not working like i would like it to work. Mind you that the capsule the first time was blue, now its orange, does that do anything also?
