I don't like being slammed on an open forum when I am sharing my experiences which were guidance from my GP for my particular circumstances.  Without a very support GP who had time to listen I wouldn't be here.  He saved my Life as well as my marriage ......
I also have experience of speaking with other people addicted to various medications who have all been given similar advice.  I worked in the NHS as a medical secretary for many years so was involved with quite a few different situations.  
Off to start another thread  

No one needs to take my advice without consulting a health professional.  It is up to the individual to take what they read or are told and see if it will help their particular situation.  I have not given out mid-leading information, a quite strange statement.  It is not based on 'purely' anything.  
I 1st tried 
Rescue Remedy years ago when it was recommended to me by a Pharmacist.  I never looked round to see if it worked/not.  I used the spray when anxiety was threatening then got on with the day, realising later that in fact, the anxiety hadn't ballooned.  Phew.   I still use it if I think a situation will cause me anxiety .......... I'm not a great fan of 'alternatives' nor do I say if it works for me but each time, the anxiety hasn't manifested itself.
However, when anxiety strikes it floors me: there is no background warning: to the point of being suicidal which is when the emergency drug is necessary.  Relaxation and logical through processes go out the window

Someone once told me Abba Fan that a panic attack only lasts 30 mins. at most as the body and brain can't sustain such high levels of anxiety, I could have kicked her into touch.  I walked out of that session straight to my GP ........ my longest attack was for 2 nights and 3 days; November 1995; and I shook so badly that my bed moved across the room.  I never want to feel that ill again.

From coping with anxiety such as pre-exam nerves, pre-driving test nerves, moving house nerves, it took over and almost ruined my Life.  I never thought that I would leave my house again ..........
