Hi. Here is my suggestion for getting off of the subs.
Immediately drop your daily dosage to 4 mgs. Stay at this dosage for 1 week.
Next week, drop your daily dosage to 2 mgs for one week.
The following week, drop your daily dosage to 1 mgs for one week.
The following week, drop your daily dosage to .5 mgs. Stay at this dosage until you stabilize. In my experience, you probably won't really notice the drops too badly until you get down to around 1 mgs, but it should not be too terrible; you can adjust the timeframes i've suggested to accommodate your personal experience. Essentially you want to remain at each dose until you stabilize on it. It will not be completely pain free, but it should be doable.
The week after you drop to .5, I would alternate days of .5 and .25 for a week or 2. Then drop to .25 every day for a week or 2. Then stay at .25, but begin dosing less frequently, i.e., .25 every 36-48 hrs. Then try to do something like .25 every 2-3 days. Then make the jump.
Like i said, this will not be pain free, but it should be relatively easy to reduce amounts until you get down to less than 2 mgs. Then just take it slow and continue reducing regularly. Be strong. You can get through this. As others have said, when you get down low, you may wish to throw some other substances in the mix. Loperamide is very helpful. The occasional benzo, etc. can be helpful in moderation. There are numerous threads on this, so just do some research, and you will be able to get off the sub without going through absolute hell anyway. Good luck!
