I'm thinking you can use 4mg the first day of WDs (wait until WDs), even if you exhibit some further WD symptoms, take only 4mg more as needed, during the first 24-hour period of true WD symptoms. Following that, day 2 will be a bit more difficult, so count on 8mg again, used at one time. The following day, try and use 4mg to get by, if necessary, use 2mg more (this plan calls for you stretching your 10 8mg). Again, next day, 4mg, using no more than 2mg to calm symptoms (OTC remedies to sleep and control bowels, though I doubt bowels will be an issue, and sleep WILL be an issue). Continue for the remainder of the subuxones with 4mg, 2mg if you can get by (the half life of this drug is insane, and you should get by on the 6mg last day to 3 or so days, with 2mg a day). Then, after 3 days of 2mg, cut to 1mg daily, adding 1mg if needed. Save the codeine for 36 hours of obvious WDs when subs are finished. Use no more than 200mg a day, which should give you a solid 7-day period (with a few mgs over the 200mgs a day when necessary). You will be fine...most of it is mental, which becomes the hardest part when the program is complete.
edited to add...take the xanax at low doses during the day (you should not need them during the sub period, save them for the codeine period) and seroquel to sleep ,...save all of the nonOTC drugs for the codeine period...
Good luck, keep us posted.
