Ezra Klein has a nice column on how you might keep yourself from overeating this Thanksgiving.  I cannot actually recommend my current strategy, which is to get bilateral un-crowned root canals1, so that you have to spend the next three weeks eating only foods which are squishy.  But it does seem to be working.

After all my teeth are repaired, I am going to track down the dentist who did both fillings and give him a sound lashing with my portable waterpik.
