My 27 Yr Old Is Withdrawling From Soboxen And This

my 27 yr old is withdrawling from soboxen and this is day 5. she cant sleep because her legs, arms and back hurt so much. is there anything i can do for her. heating pads and hot baths work alittle but not much. the only thing i can do is have her smoke pot but she only sleeps for like 15 minutes.
