I had this post saved also, from someone who posted a tapering schedule...there is yet another one also besides this one..but her eis one of them, I will try and see if I can't find the other as well. Hope this is of some help:
Tapering is the best way to go, and you have the right idea, because cold turkey nearly guarantees failure somewhere down the line.
Here's some advise you may want to consider. You are tapering too much at once. If you are taking 10-12 7.5's a day, that's approximately 75mg of hydrocodone per day. I recommend the following schedule, it will lead to very little withdrawls and allow your body to adjust.
Here goes:
Day One: 75mg
Day two: 74mg (take a razor and shave off approx 1mg of a pill
Day three: 73mg (use the razor and shave off some more...
Day four: 70mg (shave off some more)
Day five: 65mg....
Day six: 60mg....
Day seven: 55mg....
Day eight 50mg...
Day nine: 45mg...
Day 10: 40mg...
Day 11: 35mg...
Day 12: 30mg....
Day 13: 25mg...
Day 14: 20mg...
Day 15: 15mg...
Day 16: 10mg...
Day 17: 5mg...
Day 18: 4mg...
Day 19: 3mg...
Day 20: 2mg...
Day 21: 1mg....
DAY 22....YOU ARE OFF THE HYDROCODONE!
Three weeks may seem like a long time, but this is the most painless way. I am currently on 16 (two 10's) and have suffered NO withdrawls to date. During the afternoon hours, I crave some more mg's, but I just get busy doing something and in about 5-10 minutes the urge goes away.
Don't shock your system by drastically taking away such a very powerful chemical - it could be dangerous. Try the 21 day taper and I bet it works for you too.
Good luck - you can do this!
