i'm sorry you are going through this.....i have no experience with heroin addiction.....but i just wanted to say that you can make it.....take the advice of the wise people here.....they know what they are talking about....and i have heard very good things about sub.....a friend of mine used it to successfully beat her codeine addiction.....
you are in my thoughts today, and i'm hoping that you make it.....so many of us have.....it is not impossible....good luck...
hugs
ayla
