I got a fever last week, and it lasted just about that amount of time as well, however unlike most people I didn't stay home and rest, and I still went to school while feeling like utter crap....
anyway main point is, I lost my voice due to an enormous amount of mucus, if I clear my throat I get it back, but it doesn't last for long, it is better than it was a week ago, So I'm suspecting that in a week or two, hopefully less, I'll be able to voice again, but until then I'm on break....
Also the 3DS is freaking awesome, just wanted to mention that randomly
