The practice I use is a technique developed in the chiropractic profession called Neuro Emotional Technique, commonly referred to as NET.

I'm well aware that chiro attracts much contempt in forums like this one, and indeed I'm not in any way a devotee of chiro generally (anymore).

But I was made aware of NET when I was trying chiro as a possible treatment for my condition, and found that whilst conventional chiro didn't help much, NET helped a lot.

I've since learned how to do it myself without the help of a practitioner, so I can do it daily without having to spend the time or money visiting a clinic.

I've also found my progress has accelerated since I started doing a particular kind of yoga called Kundalini. I now try and do that daily too.

NET is just one of many techniques for improving the subconscious mind; others include more traditional practices like meditation, hypnosis, prayer, as well as more recently-developed ones like neuro-linguistic programming and emotional freedom technique ('tapping').

But I've tried all these over many years, and NET has been by far the most effective.
