Not our brief. Some of us do it, but not all.
There’s no official qualification in hypnotherapy. Anyone can practise, and many do.
Check with your doctor.
Beware of quacks.
FESH is the governing body for stage hypnosis in the UK, and as such it only covers hypnosis as entertainment. Many of our members practise hypnotherapy, but this is independent of their membership of FESH.
