The results of my DNA testing, showed that I am a ultra rapid metabolizer. My adhd is severe that has caused many problems for me. After proper diagnosis, adderrall xr has gotten me back to where I feel somewhat better, however, my body breaks the medication down as fast as it hits my blood stream. My dr has been willing to have me try different routes, as I do not want to go backwards. Does anyone have a good way or suggestion on how to take the 2 drugs actively together?
