I understand what you are going through, it's scary, I know because I did the same thing back on 2002. I was hooked up in Fioricet since 1999. One fine day I was so think about me as a junkie, because I could not quit by myself the use of this drug for migraines, and to make things worse, I did not have a job and neither had Insurance - so as I live in Miami, there is a hospital that I decided to go to and thru ER they check my blood to see the amount of butalbital I had it on my system and at the end of the day I was inside a detox center.
If you can only say the city you live I might be able to research some good help for you.
the detoxing was very hard but at least I got over that drug and also cleaned my system - Yes, I almost forget to tell you that I stayed in the hospital for 15 days, time to detox my system and than I got a job and insurance and started to see my doctor for continuously help. Because even after you got clean you can NOT use that drug anymore, because your body already has been addicted to it before. So if you want to talk about it, just drop a note and I will sure help you and share my experience with you as well. Because I imagine that you must have a lots of question regarding the treatment and the withdraw, etc.
Hope to help you better.
Hang in there - there's hope for sure.
