A friend of mine mixed some antidepressants anxiety pills and muscle relaxers while drunk about 4 days ago. without giving too many details she passed out and was very weak and tired with chest and throat pain. she was taken to the hospital and all tests were done and she was sent home when the dr said everything came back fine. but like i said its been 4 days and shes still having the same signs. does anyone know how long these effects will last ? shes no longer taking any pi;;s havent been for years they were old.
