I read some of the comments and my heart goes out to everyone.I wish I had a secret remedy I could hand on. I can recommend reflexology for complete relaxation therapy. Also see if you have a 'walk in' healing centre near you as they are often given free with perhaps a small donation.
Today I am having hypnotherapy as somewhere along the line my 'go to sleep switch' has broken. I am hoping that the hypnotherapist will be able to tap into my subconscious and release it for me. I will keep you posted on that.Have had a few lovely nights sleep with sleeping pills but they add to my anxiety as they are addictive and should not be continually used.
