Self Detox Question......Please Help!!!

After a workman's Comp injury (and if you been there you know the LONG delays can be before your treatment is approved) I was prescribed pain medication by my doctor like normal. He had me on all sorts of stuff. Started with low doses of Vicodon then moved to low Perc's to med range ones so on and so forth. During the 2 year process of waiting for claim approvals and 3 different surgeries I was then moved to harder stuff like oxy's, morphine etc. I was hooked! I began noticing over the last handful of month’s major mood swings that came as quickly as they left and me saying and doing things that...well just wasn’t me. Anyways, one time I was on my way to a friends house (more like down the street from his house) and I noticed I had forgotten my meds. Needless to say, I turned around and drove 45 min. home because I HAD TO HAVE THEM WITH ME AT ALL TIMES. NO MATTER WHERE I WAS OR GOING, NO MATTER HOW LONG I WOULD BE GONE FOR. That's when I realized enough was enough. At first I tried quitting cold turkey. Day 1 not to bad, day 2 minor withdraw symptoms, day 3 was unbearable (depression, the runs, headache, insomnia etc.) so I used. And then it hit me. One time my doctor gave me a scrip for Methadone 10mg. When he did I had never heard of it so thru it in a drawer never to look at it again. Well I found this drug a month ago and out of curiosity began doing research on it. I found that in addition to it being used to control pain, it was also prescribed to opiate and heron addicts. I also read that if taken properly (and tapered correctly) it could relieve the majority if not all withdraw symptoms caused by years of abuse. So (like any wuss not man enough to accept the consequences of his actions) I decided to take it. At this time, I have not had any opiates nor the cessations to take any. The scrip was written for qty 50 and I’ve been taken two a day (early morning and again in the evening) for the last 13 days. I was going to taper the balance but know taking too little causes EXTREEN fatigue and am wondering: Can I stop taking them all together instead? I mean is 2 weeks really enough to cause problems? Meaning is it possible my body is already dependent on this drug after such a short stint? Also if I understand how Methadone works, the 2 weeks without opiates should of been enough time for my body to be use to life without them in my system cause all the Methadone does is trick your mind into thinking your still taking them even when your not right? I just want to move on with my life never to deal with this bs ever again. I will pray for all those who are going thru this and hope you know you can do this if you want it bad enough.
