I was on it over a year but I do recall reading something that it does lose it's effectiveness after a short period of time.
i was weaned off the stuff about 8 months ago. Guess what I'm back on it. Fun! I don't know if it's regained it's effectiveness but I've got other issues going on as well. Who knows.
