Maggie and all others on sub or considering sub treatment:
I read something really interesting that i wanted to share about tapering the last two mg off of sub. I hope that it helps or at least touches on an explanation for why its so difficult to taper from 2mg to 0mg.
First let’s agree that withdrawal is subjective and “bad” withdrawal to one person might be “nothing” to someone else, and the opposite is true too. But too many people have reported difficulty tapering the final 2mgs, for that to be the only reason. No, some, if not most, people really do have difficulty on that last 2mgs. Why? Well first we have to understand that 2mgs is still a very significant amount of opioid. Therefore, it can maintain a fair level of physical dependence. In a PET scan , it shows available mu receptors at various doses. A significant amount of receptors are occupied even at only 2mgs. The scan also shows that in the brain there is virtually no difference between 16mgs and 32 mgs. Theoretically, a patient could dropp from 32mgs to 16mgs and not notice a difference. But as the doses get lower each drop become more significant. So it is expected that the lower you get the more you will notice drop decreases, because a higher percentage of receptors are affected with linear dose decreases. This makes it clear that it is expected to get more difficult to decrease a dose comfortably the lower you get, and 2mgs to 0mgs is the lowest you get.
Withdrawal is caused by changes to the brain resulting from tolerance/physical dependence and addiction. Buprenorphine suppresses these symptoms of withdrawal that would otherwise exist. Withdrawal is not caused by the drugs exiting the body but rather the brain changes that are left behind. While in treatment these brain changes, that existed before starting buprenorphine (suboxone or subutex), will remain, but they will not cause withdrawal symptoms because the bupe will suppress them. While in treatment and with time and by changing your behavior and thinking, your brain will begin to change back. If it were to change back 100% completely (which it doesn’t) and you discontinued bupe, you would not have any withdrawal because the brain changes that cause withdrawal would not be there. What happens is something in between. Many of the brain changes change back closer to pre-addiction status, while in treatment. If you taper off before enough changes occur, you will feel the affects of withdrawal that the remaining brain changes cause. If enough changes have occurred, the taper will be much less eventful.
People having an extremely difficult time tapering the last 2mgs are tapering before the brain has had time to change back. There are still too many brain changes ready to cause symptoms of withdrawal as soon as there is no bupe to suppress them. A longer or different treatment is needed. Even when someone does everything right there are still some brain changes that will not change back until someone has been off of all opioids for a while, these are the changes specific to physical dependence (not addiction) and they tend to get better in a few weeks.
Everyone is different and evaluating how altered your brain is from addiction is tough, also estimating how fast it will heal is equally tough. That is why the better treatment plans don’t have fixed treatment duration. Pacing your taper with your brain’s ability to heal is essential if you want a comfortable taper. Other things besides time help “heal” the brain. Changes in environment, behavior, routine, all help. Counselors/therapists can teach you how to think differently and stop compulsive thoughts. Things that don’t help are replacing the compulsion to do drugs with another compulsion (any compulsion) or constantly thinking about drugs or activities or people you associate with them. Basically what you want to do is help your brain forget as much about drugs and the ritual of it as you can.
So if it is extremely difficult to decease your dose from 2mgs, it might be a sign that a longer or different treatment is needed. It is also thought that some people will not be able to repair enough of their brain to ever feel normal without some kind of opioid supplement. These people would never be able to taper off of any opioid comfortably. 2mgs is a significant amount, don't think "oh, its only the last 2mgs I already dropped 14mgs, this should be nothing." According to the PET scan, 2mgs affects more receptors than the whole 16-2mg drop did.
Thought it was a good read.
How are you doing today?
