Well, see when I switched from Concerta to
Adderall, I just stopped the Concerta and went to taking the
Adderall XR. After a few months the XR did not seem to work very long or throughout the day. So, in 2007, I went on Adderall short acting pill form which generic form is amphetamine salts or amphetamine mix tabs. With this pill, first of all, it is extremely inexpensive. I pay $30 for 180 tabs 20 mg each. I cut each in half and take each half 4 times a day a total of 40mg.
