You have really got to want to stop using before you will make progress.
Suboxone gives you the right state of mind to make that decision and progress to sobriety.
It allows you to feel like a normal human again, and allows you to get back on the horse. (So to speak

)
The aim of Buprenorphine treatment is:
1. It will stop other opiates from working. If you do manage to break through, it will be followed by a period of withdrawal, which is an incentive not to compromise your treatment.
2. Buprenorphine should hold you completely, meaning that you should not need any more medicine to feel normal.
3. The half life of Buprenorphine is long, very long. This means that you should not get inter dose withdrawal symptoms. A sub doctor I visit has suggested that you can dose every three days if you like. This makes for easy treatment.
4. The safety profile of Buprenorphine is amazing. It is quite safe in overdose, without the respiratory depression of other opiate drugs. (Except in combination with Diazepam)
5. Buprenorphine has been shown to act like an antidepressant, which can really help things along during treatment.
I am surprised your doctor did not mention this treatment option.
You should be aiming to get back into normal life. Integration is the key, not the drugs you have to take to enable it.
