<p>Hi. Does anyone know if Adderall can cause physical fatigue?</p>
<p>well, i guess it depends what you are taking it for. </p>
<p>for ADD kids, it calms you down, so I could see that</p>
<p>I'm narcoleptic, so I take it to actually keep me awake</p>
<p>However, it significantly raises your heart rate which makes physical activity more difficult and can lead to fatigue. I'm pretty sure it can cause muscle weakness/fatigue. </p>
<p>Ask a doctor WHO KNOWS WHAT THEY ARE TALKING ABOUT!!</p>
