I'm glad you brought it up! I encourage people to also do their own research too, google studies for any drug you wish. You may be surprised. Where does this "off the shelf" stuff come from? Big Pharm representatives who stop by your doctors office to provide their studies and suggestion for other uses. I was horrified with some of the side effects I read about. Yet they were deemed more preferred then safer "addicting" drugs. Also of interest, look for independent studies where they compare different drugs with the placebo. It's pretty interesting to say the least and a real eye opener.
