My sister has had drug problems in the past.. and just got out of her outpatient program a couple of months ago.. but she was just caught with six needles in her dresser drawer. she hasn't admitted to doing heroin, said that she was only dealing the needles.. which we all know [my family] is complete bull. but now she's been grounded and home for the past couple of nights.. and keeps complaining that she has restless leg syndrome and can't get to sleep until six in the morning. now, i know that RLS is a withdrawal symptom of heroin.. but if she's having this every night, does that mean she injects sometime during the day, and then gets these symptoms each night due to that? or, [and this is what i hope] has she stopped using for a couple of days, [a week maybe] and these symptoms take a while to shake off?
