Here's what I know about it.
I just went through detox for H and I had used it for about a year. I have used opiates during most of my life as the environment for pain meds was much looser years ago. So! I do not recommend cold turkey as it is a living hell and most are not able to gut it out unless jailed or otherwise detained. But if I were to try to do it at home, and I consider this to be very risky behavior, first I would obtain something to keep my blood pressure down. Clonidine is most often used in detoxes. Then you have muscle relaxants, antihistamines, nausea medication, anti-diarrhetics (SP?) If you can obtain an amount of benzodiazepines such as valium, clonipin, what-have-you you will have a simulacrum of a medical detox. Of course, you will be playing doctor, and you could possibly over-medicate because hey, we are addicts that's what we do, stop breathing and die. I recommend asking other users where the best local detox is. It is still hell, but you aren't going to die and you might actually be successful. And then directly from leaving detox, find yourself a 12-step group that resonates with you and attend as if you were trying to save your life. I have 39 years of unsuccessful attempts to control my opiate yearnings, (along with many other substances) but I have failed repeatedly. The only successes that I know of other than a few anomalies, are those who hooked up with recovering whatevers like yourself that used like you did, and took the suggestions and did the work. Most resist this and go back and suffer the repeated hells of opiate withdrawals and addiction until they are successful, or they OD and die, or die of complications of their drug use. It's a grim thing. Playing with suboxone and subutex is a dangerous game. Doctors must receive special education to even administer it. Of course, insurance and money always are in play as well. I've wasted my entire life trying to find a way to either stay clean or successfully use. To sum up: to get through withdrawals you have to keep your blood pressure down. That is the horrible jangly feeling. Your muscles, including your gut muscles will cramp. It hurts like hell. You will get diarrhea, your bones will ache. You can only treat the symptoms to the best of your ability or go to a medical detox. I went 5 days once trying to kick opiates because someone told me withdrawal only lasted 3 days. By the end of the 5th day I was screaming for relief and have a morbid fear of withdrawals. My healthy fear of doing crime for opiates and then subsequently getting thrown in jail for said crime has kept me from having a huge problem (because you get thrown in jail and withdraw with no help, typically) but it's been bad enough. I could not do it at home alone and I know what to do. It's very, very tough. Take the tapering route, with a medicine you know the strength of or get help. I wish you the best. Every state is different in their approach to treatment but the privacy laws protect you somewhat from the stigma attached to addiction.. Good luck in your search for relief from opiate addiction. Also, beware of addicting yourself to benzos, which is it's own special hell, while self-administering in an attempt to quit opiates.
