Hi There, I was diagnosed adhd a few years ago. Last spring I was put on levothyroxine because my TSH test came back high. It is now just under the lab's standard so the Dr. will not look more closely at my thyroid. I am still so tired all of the time though, even when I am taking my adderall. Does anyone know if the adderall could be messing with my test results and making it appear as though I have better results? Darci
