Crest Whitestrips make me produce excessive saliva.  I am not sure if that's normal or not, but I am sitting here with my mouth totally agape for the past 10 minutes because closing my lips around my strip-covered teeth just feels bizarre.  And I can't talk right.  I sound like that drooly kid from Hey Arnold...  Brainy..?  Wow, remember Hey Arnold??!  Ah, memories...  My jaw is starting to hurt.  Not sure how I will make it through the rest of the week doing this twice a day.  I guess we'll see.
