It's always different. I chased that damn dragon for 15yrs.WDs aren't so bad anymore. Get yourself 3-4, maybe even a week, of free time some herb and some benzos (like VALIUM - long haf life) and sink into your Netflix.
Tapering off is always best. Tramadol helps take the edge off. Suboxone or subutex is even better. Just stay hydrated and and eat even though you won't want too. Force feed, as well as, shower regularly. You won't want to but it will make you feel better. Soup always helped me or nutrifast / Slim-Fast ready to drink meals are a life saver.
CYCLOBENZAPRINE should help with cravings, if you can find something to help you with your blood pressure that will help, and maybe some Midol for the stomach cramps.
It can take anywhere from 3-4 days to a month, but at 2 bags a day you should have much more then sleeplessness, diarrhea, cold hot chills and some, irritability to look forward too.
Best of luck brother...
