I got mine filled on the 18th of this month from walmart.. Its HORRIBLE! I am not convinced that it is even close to being a replacement for the name brand adderall.. I can't stay awake, feel cranky/moody, headaches that won't go away, shaky, I can't find barely anything on the internet about this medicine either.. Its a white stop sign shaped pill marked m in a box on one side and a 20 on the other.. Anyone else have any issues??
