not likely to die, though your definitely going to feel like it and at those doses the typical wds aids become far less effective and the options are fewer. Finding some benzos should be your highest priority, followed by the best sleep aid you can get your hands on. Immoduim is likely going to be your new bff for the next several days. Kickin from doses that high is going to more hellish in the beginning as it's going to take longer for that much oxy to leave your system. I'd start drinking water and get use to the idea that the john is going to be your other bff for the near future. If you happen to have any sub to help you kick, your only begging for precipitated wds if you don't wait at the very least several days for the oxy to get released from your body. Hopefully you have prepaired yourself with some forms of detox meds before starting this kick. Your not doomed to fail because of the size of the habit, it just may be a little longer than those of that have kicked from a lower amount. I'm not sure what your situation is and how prepared you are going into this. Just be smart about it, if your really starting to suffer, much more so than the typicl hell that is cold turkey, get too an Er if your BP reaches dangerous levels.
In fact, it couldn't hurt to seriously consider getting through it much easier and far sfer with the assistance of a medical detox, most cities have free programs funded by various churches, health and community services. I've seen a few people kick from similar size doses,yeah it took a while longer, and it hurt for a good 5-6 days, but it's not impossible. If your losing fluids from every single orffice possible, hydration is going to become critically important. Hopefully you have what you need to induce a long period of sleep, thats about all I can suggest. There's always more people kickin in the TDS, you'll get more suggestions over there. Good luck.
