"The first few days was awful, I was in such a pain that I only took my tray out twice everyday to avoid the pain. Because it was Christmas holiday, I had one day that I only wore the tray for around 18 hours, I extended my time on this tray to 3 weeks according to my dentist.\n\nThe last few days were so easy, that I can take them out without any pain at all, I guess it just happen to everybody..."^^<http://www.w3.org/2001/XMLSchema#string>
