I have take Adderall for ADD and went to pilot medical solutions and they sent me an email saying this.

Thank you for your inquiry to Pilot Medical Solutions (www.*************).
While we can most likely help you gain FAA approval, the medication
which you submitted is disqualifying. In addition, a medical history
requiring this medication poses an obstacle to certification even if this
drug has been discontinued. Aviation Medical Examiners are not
authorized to issue certificates with these issues. They must defer the
application which can take 6 months to a year without our service. In
addition, your medical history will require special issuance of a medical
certificate under Federal Aviation Regulation 67.401 (see:
http://www.*************/special_issuance.htm).

I understand that I must get off the medicine to get my medical. Is their any possible way that I could get the SI off of my medical? Would I have to get a letter saying that I have outgrown the ADD? Or would I have to have a letter saying that I was misdiagnosed? Also, would the AME have any say to whether an SI should be taken off.

Best Regards,
Robert
