I agree, the victory is won through Christ. That does not mean spiritual warfare has ended. Think of it like this, the war has been won but we still see small skirmishes or battles and there will still be casualties.
I have found when I make a big move towards Him in my walk that is when the attacks come. I am pretty well left alone when I am not a threat.
Remember Job was a holy and righteous man, yet he was attacked. I think we need to look at why we are attacked. God is still our God, even in distress. So instead of praying Lord get me out of this, pray Lord what is it You have for me in this? What am I to learn? How will this be used to glorify You? I know I rest fully in your hand and I don't always understand the why of things but I know that You are faithful to Your children.
As to the OP and your addictions, I want to encourage you. I was a drunk, no doubt about it. When the time came and I turned fully to Him, alcohol was one thing that was no longer an issue over night. The other things I still struggle with I give to Him daily. God works in His time, so continue the fight and be aware of what He has already delivered You from.
A good exercise when it seems that we are just spinning our wheels:
Think about where you were a year ago in your relationship with Christ,
Write down all the tough times and struggles that occured through your life...then write down what God did for you in each of those times (this is especially encouraging when we look at those times when things seemed most hopeless)
Rest in the knowledge that God is still God and be at peace (contentment) by brothers and sisters.

The warfare to me is between the Flesh and the Spirit (Romans 8)
Our flesh desires to do wrong, but our spirit desires to do the will of God.
We have to mortify the deeds of the flesh, and put it in subjection.
This is what I meant when I said if I wanted to see a Demon all I had to do was look in a mirror.
Myself (My Flesh) is my own worst enemy.
I feel like Paul
(Rom 7:18) For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
(Rom 7:19) For the good that I would I do not: but the evil which I would not, that I do.
(Rom 7:20) Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
(Rom 7:21) I find then a law, that, when I would do good, evil is present with me.
(Rom 7:22) For I delight in the law of God after the inward man:
(Rom 7:23) But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
(Rom 7:24) O wretched man that I am! who shall deliver me from the body of this death?
(Rom 7:25) I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
