To the OP: Allow me to describe what hardcore opiate addiction withdrawals do to you. First you'll start to feel itchy, dirty, sweaty, maybe so far as unclean. Your skin hurts. The cold hurts your skin, any texture hurts your skin, it just doesn't feel right. It feels papery. Many people feel like puking, I only get that feeling because I lose my appetite, and when I've missed enough meals I begin to vomit. If I smoke pot the vomity feeling will go away, but the anxiety level may rise, a risk I usually take. I do get nasty diarrhea, from anything I eat, for about 2 weeks to a month depending on which opiate I'm coming off of. Depending on the opiate (ab)used my bones might hurt the way they did like when I was a kid, dealing with growing pains, only x1,000,000 worse, or it may be my muscles that won't stop twitching and cramping. Absolute despair and anxiety. Insomnia kicks in. And for me, one of the worst is the sweats. None stop 24/7 mainly armpit but also face/forehead sweating. And Cold Sweats, being freezing cold yet so hot you're sweating at the same time.
