Nbc channel symptoms and conditions

I've noticed that NBC and The Weather Channel appear to be two of the biggest advertisers of Singulair. NBC can always be sure to have one on during the evening news, at least here where we live, on our local NBC channel. There for awhile, I was logging what time, and what channel I saw the ad. The ad only lists the basic side effects that aren't even dangerous. Merck must be paying NBC the big bucks because they still haven't dropped it. I don't know, should we bombard NBC with letters of negativity or boycott or something to get their attention on this murderous drug?
