anxiety
"I have had anxiety all of my adult life, and at times I have been almost crippled through panic attacks and nervous tension. I have tried nearly every benzodiazepine available, and for myself diazepam is by far the most effective, safe and trusted. It is also a very good 'all-rounder' tranquillizer, useful for anxiety, panic, insomnia, muscle tension through worry, tension headaches and irritable bowel syndrome induced through anxiety. I have never become addicted despite years of use, I mostly take diazepam only when required, but several times when going through a particularly bad period of anxiety and depression I have taken it regularly for several weeks and I didn't experience withdrawal upon discontinuation."
