I'm sick with a really bad cold and I just woke up. My mouth feels so gross. Time to give my teeth and tongue a good brushing to remove the gunk. My nose is also so stuffy so I know when I gag a bit on the toothbrush it should clear up my sinuses a bit. The snot really gets going towards the end. I give my nose a really good blow to clear. No tissue of course. After I clear my nose of as much snot as I can, I wash my face.
