For the drs. out there, why do doctors perscribe downers more than uppers??

I find that most doctors are willing to basically just hand out downers, but what about a person that has a hard time with being tired all the time?
Just curious, found that amusing after my last trip to the doctor.For the drs. out there, why do doctors perscribe downers more than uppers??
Prob. because a lot of people are "stressed" out and already agitated enough as it is. ergo downers..if you are tired all the time to begin with could be lacking in sufficient vitamins or anemic etc. For obvious reasons you shouldn't take both.
Because if you get hooked on downers, they can start prescribing uppers.....win win situation.
