Morphine
"I get the generic brand from Teva and take two 60mg tabs in the a.m. and two 60 mg tabs in the evening.  I find that the generic wears off too early probably 1 and 1/2 hours early and when pain is severe l need something else as well.  Maybe the generic is not as good as brand name so l wish l could try the brand name so l can find out."
