Normally herion gives me energy. In the 4 years I have been doing it (I have never shot it, and never will), it has never done this. This batch is very white, when it has always had a gray tint. Even if I use a very small amount (even using a quarter, or less, of my normal dose) it makes me tired. I am not "nodding", just really tired. I could easily fall asleep if I wanted to. Any ideas?
