When enough?
What convinced you that it is enough? You might realise you are consuming too much, but we all know its not possible to quit before you are really committed. When does 'normal' consumption become abuse/addiction?
I witnessed a horrible car crash caused by a drunk driver, I was one of the first at the scene. My hands were shaking when I drove off after my help was no longer needed. Luckily as far as I know nobody died.
