Pretty difficult to do heroin in moderation. There's that dope sick thing to consider as well. I only did heroin a couple times and I hate needles so there was that to consider. But I liked it. I liked pretty much whatever was in front of me. July 25 will mark 20 years since I've put any drugs or alcohol in my system. This is a good thing. Moderation just never worked for me and for many people it never can or will. If you have the constitution to get high or drink in moderation,good for you. I'm a horrible drunk and drug addict and my I don't miss anything about that life. Not a thing.
