I listened to Heroin in the dark on my bed. During the initial dosing my arms felt heavy and I felt waves of heat go through various parts of my body. After the dose ended I continued to lay in my bed for a few seconds without any real thoughts. A blank "brain turned off" kind of feeling. I then stood up and kind of lightly stumbled downstairs. My dad and I exchanged a few words but as I was talking with him I kind of stopped in mid-sentece, as if not to care to finish it.
It was nice. Shame it was not longer though.
