Stuck: How long ago were you on 700-800mg of oxycodone? And are you getting your subs and xanax off the streets, or from a doctor? Have you ever gone through full blown withdrawals before? I know it's probably hard to think right now, but try and gather all your strength and call the local number for NA. If wd's get too bad, vomiting and diarrhea, go to an ER because you can get dehydrated quickly if you can't keep liquids down. Please let us know how you're doing.
