I am looking to see if anyone had this happen recently. I filled my script for 120 10MG Adderall IR. The brand is Teva or I think what used to be Barr. I had the same brand for a while, but this time I took my normal dose, and nothing at all! I actually am prescribed to take 2 a day twice a day, and typically I only take half and have energy. I've taken 2 and a half twice and had no effects at all. Anyone have any idea whats going on?
