I also am on long term maintenance and must take a holiday yearly. This is the schedule and suggestion(s) I can offer,hope they help.You must have self-discipline,NO MATTER WHAT,it will pass,dont take a hydro.

Day 1: 10 pills a day
Day 2 thru 6: 7 pills a day
Day 7 thru 12: 5 pills a day
Day 13 thru 16: 3 pills broken in half a day
Day 17 thru 20: 2 pills broken in half a day
Day 21: Your done.

Make sure you have enough tabs to begin,do not take a missed dose,sleep as much as possible and valium/xanax
helped me thru it. Be careful(discipline again) not to exchange one monkey for another If you have errands/work during the tapering,only take with you the alloted number of tabs for that day,or your next scheduled tapered dose.
Hope this works for you as it did me. I cant take credit for this schedule, a friend passed it on to me,so what goes around comes around, as I pass it on too.
