I have been on Adderall for a few years now and just this week got switched to XR. I took 60mg on Wed and 60 on Thurs. Thurs night I was having Audio and Visual Hallucinations. I did a search and it said that it is caused by overdosing on Adderall. I have taken up to 200mg a day of Adderall but when I took the 60mg XR I have had all kinds of scary things going on. I am now having cervical spine nerve damage and wonder if Adderall could have caused this damage?
