Hi All,Have read about quivering lips a lot lately on the Board & thought I'd share my recent experience. I've had the quivering lips on and off while smiling but today, I felt feverish and started to take my temperature. I was busy and getting annoyed by how long it was taking for the beep. So, while holding the thermometer with one hand I was trying to look down to see if the digital numbers were still moving, (or if the battery was dead) and my lips and the area above my lips started quivering ALOT! I guess because of the odd way they were around the thermometer and then the way my eye and cheek muscles were when I was trying to look down. It brought back memories of how it has quivered for years whenever I do this, (get impatient and start trying to read it while it's in my mouth.) Now, hours later.....my lips feel funny and, if I don't distract myself I can probably make them quiver when smiling. Just wanted to share this because I know it's happened on and off for years. Hope this helps anyone. Denise
