I wasn't trying to kill myself, but I had starved myself for roughly a month or so before I was involuntarily admitted to hospital for anorexia. You'd think it would be kind of painful but the thing is after a while your stomach actually shrinks to adapt to your diet (that is what I was told by doctors, and my experience suggests that it is the truth, but someone correct me if I'm wrong) and before you know it a single bar of chocolate will fill you for the day. Hunger pains aren't the issue but the tiredness sure is. I suppose the number one issue with starvation is that it takes ages, although I've often thought that, if I wanted to, I could probably do it easily.
