Best advice I can give, having gone thru this once a month for years until I finally quit, is to perform a version of the rapid-detox method at home - preferably with a sitter or someone to check on you. Basically the idea is to sleep through the worst of it, particularly the first 3 days if at all possible. Understand that different opiates have differing half-lifes, and though you think you may be in withdrawal if you miss that next dose or so, the worst typically comes 24-48hrs later. IMHO, the best thing you could hope to get a hold of is zolpidem from the school med dept. That will usually (with alternate ROA...) allow you to sleep through anything. These alone would probably do it, but the other component that allows compressing this whole process into the shortest period of time (say, a weekend) is buprenorphine - which is a bit harder to come by. I don't advise asking for this one, try to source it elsewhere. If used while still somewhat under the influence of other opiates can and will throw you into something called 'precipitated withdrawal' - which is nothing anyone should ever experience (at least not while awake). Typically a 24-36hr period combining these two would almost always render me well enough to maintain by monday. Depending upon the length of your dependency, you may experience PAWS for several weeks after detoxing. This is where a mild, long half-life benzo such as clonazepam can be useful - or at the least, some grass.
Going through the whole CT without these tools, and surviving it, is entirely doable, but most unpleasant. Just be sure to remind yourself that no matter how bad you may feel, it will not kill you. Benzo WD, on the other hand, most certainly can - so taper off that forementioned benzo quickly and only use it as needed. After you've made it through the process, be sure to remind yourself that you do not ever want to do that again. Because, fair warning, they get progressively worse each time - just trust me on that one.
I wish you the best of luck with it. Ramble on.
