You are a complete ass for thinking this is of an add nature.  I am very concerned about my health and have asked a very important question.  If I knew the answer I wouldn't ask.   The real problem is the amount of misinformation on the internet and because of an existing war between Pfizer and Merck for drug supremacy; the current information superficially available is slanted and not trust worthy.  Someone needs to put their neck on the line and answer the question with empirical data.  As of right now it's all about money and I personally would like to get the best health care possible.  Somebody help here... Thanks!
