Doctors simply don’t treat things well that are not classified as a particular disease. If you want to get stronger or more fit, you may well be better off asking your local bro than your PCP.
Sleep is sadly in the same category. If you don’t have sleep apnea, and you want to get treated for sleep, you will be offered any number of pharmaceuticals, all of which are terrible. Better advice comes from other people dealing with sleep issues in this case.
