Thank you Beenthere. I thought that he was not taking enough considering his amount of usage for such a long period of time. Is it possible to take the subs most of the time and then one day still be able to get high on heroin? I'm asking because when he is high he is extremely loving towards me. And typically he is not. Since he has been taking teh subs he has acted the same way he does when he is high. So it's very difficult for me to even tell whether its just mood swings or what. Thanks for you reply and support!
