Yes, Rusty I will tell you the trick....You have to wean yourself down over the next months to an amount of about .5mg or less, and you will go through some Bupe withdrawls, which from 8-16mg a day to nothing, you would be having worse withdrawls than shooting a gram of dope everyday, BUT if you taper right and low enough you will be just fine.
First thing you have to you is stop shooting though, you are addicted to this action, and the rush of bupe over your receptors, I promise that.
I am one of the few here that has been on everything, went on suboxone, got clean completely, then always winds up back on suboxone at the end of the day because I am a pussy and cannot stand WD's for 2 seconds, and also because I have two hurniated discs in my lower back, so what is worse? Take 5-10 norco a day, or 2-3mg of bupe per day and feel 90% less pain than being completely sober? I choose bupe. I have been getting high for years, and have been over it for about a year now.... That is your #1 problem, if you aree still shooting 8-16mg a day, it dosent sound like your ready to stop getting high when you are shooting those kind of doses is crazy sounding to me

8( I went from 1g of dope a day, to 8mg the first day off, to 4 mg the second day to 3mg the 3rd day, to 2mg for the past year, Ive only recenetly come back up to 3mg because of some seriousss pain that it completely blocks.
Best of luck!
