I have quit about two years oxicodone use cold turkey and did good for about three weeks, came across some heroin at a party and snorted it, began purchasing it for about three weeks snorting the whole time, just quit yesterday (making today day two) and the withdrawals are terrible, especially the restless legs and lack of sleep. I purchased some otc legs meds and am trying to exercise. Can anyone give me anymore tips on what to do and how long I will be dealing with this.
