Here is the bottom line dude, you're gonna have to go through discomfort, plain and simple. The best thing you can do is wean down. You have to truly WANT to quit, or you will just continue to abuse it, and get nowhere. I'd find out what doses you're taking, and slowly taper your way down, and then stop. Bottom line is you're going to go through hell for a while, no matter what. The physical effects go away for the most part after 5 to 7 days, it's the psychological effects that kick your ass. You will probably experience a good amount of depression, trouble sleeping, anxiety and such for quite a while, and you pretty much have to relearn how to be happy in life, as drugs tend to take over all aspects of happiness. You are going to deal with horrible cravings and it will probably be a couple months before you really even start to feel like yourself again. I'm speaking from experience, I kicked an opiate habit about a year ago, and know the whole drill.
I'm sorry if it sounds harsh, I am just trying to be honest. It seems in society everyone wants an easy way out, and when it comes to addictions, there simply isn't. Addiction wrecks hell on your mental state especially, and overcoming it is a serious challenge. It's best to go knowing what to expect, because otherwise relapse is almost imminent if you don't realize the true challenges. You may have to put your ego aside and ask for help, ultimately you have to decide what is more important, your ego or your life? Don't be ashamed if you need true professional help, it doesn't make you a weak person.
