Denon,
Don't beat yourself up over this. I did the same thing you did. I wanted to be off of hydrocodone so badly, that I tried to make my taper quicker as I neared the end. I ended up having to take 1/2 of a pill after I had quit for a day. Everyone is right on here. When you get down to the last of your doses, they are small. So, when we cut them in half, that is a HUGE drop down.
I understand when you say that once you make up your mind to do something, you do it. That means, that you WILL do this, it will just take a little longer than you planned. I looked at it as, what is another day on the pills, compared to the rest of my life? THe slower the taper, the more your body can adjust to it.
Hang in there!! You are doing great!!!! TaCot
