My boyfriend hung himself about 2 months ago... ever since then I have been taking oxycontin to forget about the pain. I have been taking an upwards of 50 to 60 mg a day to function. Without it I feel like I am going to die. I have a huge history of addiction, starting with meth, vicodin, percocet and now oxy. I haven't had any in 2 days and I have muscle aches ALL over my body, I am tired and restless at the same time, I can't think straight, and I have missed my period (was due yesterday), depression.. . Are ALL of these withdrawal symptoms? If so, WHEN will they go away???
