"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 &#039;all-rounder&#039; 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&#039;t experience withdrawal upon discontinuation."
