Subutex and Suboxone: Questions and Answers
As to being treated by therapy,has she stated the reason,other than she knows she has a problem?Misdiagnosing your own problem and self-treatment aren't conducive to long term recovery.
NA meetings and in house treatment is suggested from the first.
Detoxing from any addiction like this can be deadly!This is a fact,not a myth.
You have to be the clear thinker in this situation,your opinions and guidance have to be the deciding factors in your daughters recovery,treat her as a baby,taking her first steps.

I hope this helps you see a little about this disease,and I will be back in the AM to see if we can discuss this further.(it's 2:32 AM my time,got to get some sleep...:) )
