Done by our beloved Government.
Here is "needs analysis" for you: Recently Medicaid refused to pay for 2 100 mg Toprol tablets my Mother takes daily. The reason? "Excceded recommended dosage of 200 mg per day". Huh? 2 time 100 is 200. Well, some Govt puke decided that taking it twice a day is a luxury, not a need. Never mind that she feels that she can't get up in the morning when she takes only one pill per day. Never mind that the regiment she is on has been developed after a year of trial and error suffering and worked for a few years flawlessly. There is no need for it, you see. The Medicaid flunky says so.
