Back to the... Tray 2

I am going to London next week, so I went to the dentist today as part of my prep for being away from NYC.  I'd expected the visit to be a short and concise one, in which I pick up Tray 4 and 5 and be on my way.  This was not to be.  It proved to be time that I got attachments for the top (uncomfortable process, but necessary), and my dentist has instructed me to go back to Tray 2 for 2 weeks -- she is not happy with the way my teeth have moved.  BOO.  That's losing 3 weeks, since I'm already halfway through Tray 3.

*sigh*

Good thing I kept Tray 2.
