A study I saw noted that the effects of Fosamax and its ilk carry on for a year or so after the pills are discontinued. Maybe that is why some docs like a holiday. It is a freebie and they think/hope the holiday gives a patient's system a "break," thus allowing them to take this drug for a longer period of time. The alternative drugs may not have a good track record for long term use.

Something I am trying to practice, "don't go looking for trouble."
