Fair enough. I can find articles about how they may be overused and less useful than thought… but you can find those sorts of articles for any medical treatment and frankly I’m not qualified to evaluate the evidence anyway. I guess I was wondering if it was one of those things that was done in the 80s but now everyone thinks it’s a bad idea. Guess not!
