"suffered a major panic attack whilst driving 6 months ago, which left me with constant severe anxiety. my doctor put me on citalopram and beta blockers which made things much worse. i was now having panic attacks, night terrors, feeling very suicidal.  i was eventually put on 2mg diazepam tablets.  this helped within 20 minutes of my first tablet.  i felt slightly less anxious and a bit medicated. continued taking 2/3 tabs a day for the next few weeks.  dramatic improvement.  when i&#039;m feeling a bit dodgy i will still use as and when needed."
