Doctors prescribe as it is easier than finding a cause for the complaint of a patient.  Doctors today remind me of one warning...."the first one is free"...which was supposedly the credo of drug dealers.  @John500AF - have you ever tried to refuse meds from your doc?  I have and was labeled as difficult.  I'd rather be difficult than take meds from someone who should not be a doctor in the first place. You do know what they call someone who graduated at the top of their medical class, right?  Doctor!  They also call the person who graduated at the bottom of the class?  Yes, you got it.  They are still called doctor!

Save yourselves!  Take your medical care seriously and don't allow your doctor to dictate your life simply as he or she is lazy!
