Still Having Withdrawl Symptoms From Percocet And Others???

Hi all, I am brand new here and have spent most of this afternoon looking through this site. Here is what I have to say.

I was on Percocet at times and the other times Morphine.. just depended on what doctor I seen... either my family dr or my surgeon. I have had two major knee sureries which required percocet and oxycontin and then I had a horrid ectopic pregnancy and was on pain killers for that... basically continued use for over a year. I also have intercitial cystitis and my family dr gives me morhine for the pain with that. The thing though is I got so hooked on them.... they gave me energy and when I do not take them I have no energy so I would go to my family dr's and tell him I needed more morphine and he would give it to me and most of the time I did not need it for pain... I only had attacks maybe once every two weeks. Same with the surgeon.. I told him my knee was still hurting and even though this was true, it did not call for percocet.. but I would tell him it did and he would give it to me.

Well, I finally decided to quit doing this stuff (after many attempts) and I ran out in the second last week of January.. I got through the three easy days (I never noticed any withdrawl symptoms till after 3 days) then I started to feel the withdrawl... all of a sudden my father-in-law was in a horrible tree cutting accident and he passed away. This was a horrific time but at the same time, I was so busy trying to be there and console my husband that I forgot about going off the meds and after a week, when everything was over I then realized I had gone almost two weeks without pain meds. I felt fine.. physically that is... now I am going through the mental withdrawl.... I keep trying to figure out how to get more and then I tell myself to stop thinking about it as I am doing so well... it has now been almost four weeks since I took any narcotics.. physically I feel fine... but I am still having thoughts of going to get drugs and how I will go about doing it...

My question is: how long till these mental urges are gone? I am so afraid I will give in to my needs and blow it...
I know it has only been close to four weeks, but I am so proud of myself for doing this but scared at the same time of a relapse.

Any advice would be of great support and greatly appreciated.
Thanks all..
