make a schedule and try to stick with it. most likely - if you are like most of the addicts i've ever known - you'll start feeling a little queasy, panic, and say fuck it to yourself and take em all.
i would concentrate on non-opioid support meds... you probably can't avoid withdrawal. but there are ways to make it a little more comfortable. that, and - this really surprises peoplle, but it is true - context/mindset or how you behave as you detox can be the difference between the kind of torture that makes you start hunting around for an easy way to off yourself and a period of discomfort that sucks, but about as traumatic as having the flu or a bad cold for a week or two.
first, support drugs. benzos - i'd go with klonopin. it's not very fun as benzos go, but for whatever reason, it's the best for withdrawal. even better is if you can get some clonodine to take with the klonopin. any junkie will tell you: those two pills have a synergism that works so well for withdrawal symptoms -opioids only, of course -that it can really make a disaster into a controllable period of discomfort. don't get crazy greedy, and i'm hoping you know yourself well enough to be able to figure out dosages yourself without putting yourself in danger... next: immodium and benadryl. both over the counter, these two handle the gastro-intestinal distress angle. if you manage to hold onto to a little bit of some kind of actual opioid, the benadryl will potentiate it slightly... if you have access to more serious psych meds and know what you're doing with them, using an anti-psychotic like serequel or zyprexa has always helped me sleep through the worst parts. but that's more for people who are already experienced with those meds. last, neurontin has proven - to me, at least - to be the most important of all the support drugs and that's b ecause it takes care of the one withdrawal symptom that doesn't seem to respond to anything and - agian, at least to me - is the most horrible, agonizing aspect of w/d... leg spasms. almost like a myoclonic jerk, these are where that whole kicking the bird thing originated. neurontin has been tried as a potential treatment for pretty much every psych issue in existence, and it's pretty much worthless for all of them, for most people. but, if you can get it, and as it's not the slightest bit abusable, you might actually be able to talk a doc into prescribing it, it is a life saver.
now back to the attitude is everything crap. it's not crap. if you refuse to get out of bed, except to run to bathroom for liquishit or pukage, shivering and sweating and stinking and twitching and just suffering... well, it's going to go exactly like that. force yourself to get up. take a shower. get outside. make yourself stay hydrated and get some food down. try to find activities that you can enjoy in a passive sort of way. it'll feel impossible to get over the initial inertia/apathy, but once you're over the hump, faking your way through your day will - not only distract you and make things go faster - it will actually make things less unbearable. swear to god. i know that sounds like some kind of casac-without-an-addiction or social-worker-without-the-grades-to-get-a-doctorate kinda bs, but as crazy as it sounds, it is really true.
use the drugs and pretend you're just getting over the flu and are a little under the weather but functional, and you'll get through it. it will be really...really bad. but not impossible. your own actions dictate your experience.
good luck
im not going to lie though i have been using clonazepam but this is while i do gear. Thats my combo of choice. If i do a dig of gear without having a Benz in me i feel a little empty. If i take a benzo without opiates around there WILL soon be opiates around lol. Also im an injector and like like i said i usually do lots of benzos before and while im having binges of injecting heroin and speed balls (when you inject heroin and crack or coke)
