Some drugs are just pushed harder than others because doctors just don't know (and can't know) all the facts. Take statins for example. My doctor and about 3 others would look at my numbers in a few seconds and just say, well lets get you on Statins. Finally found a doctor who said I can do it via eating well and told me to read Good Calories Bad Calories by Gary Taubes. Here I am years later, cholesterol numbers are literally perfect, and feel great.

I guess you need to be lucky with your physicians.
