EFT

EFT (Emotional Freedom Techniques) was originally designed to reduce the psychotherapy process from months and years down to minutes and hours. From there it was discovered that astonishing physical healings also occurred. Symptoms faded for everything from Migraine Headaches to Cancer. Complete details are given on the EFT website (see my links). It often works where nothing else will.
I have had success with cravings, phobias, pain, muscle twitching, nervousness and anxiety, insomnia and fear.
The technique is simple (it is that 'weird tapping thing' you may have seen on TV), but must be applied with careful thought to the root cause, being specific and continuing to persist until all the trees in the metaphorical forest have been felled!
