Why is COR 135 (Adderall Generic) has taken the place of Teva Pharmaceuticals USA (Adderall Generic)? The COR 135 has a bad side effect for me mentally & physically I had to travel many CVS to find the Adderall Generic Teva Pharmaceutical USA I was use to taking. This COR 135 is in all the pharmacies in Jacksonville. Why? when what I was taking work best for me
