Emotional Freedom Technique

I read about a self-therapy thing called EFT in a free New Age magazine. I went to a session with a guy called David Smith, and I found it very useful. The website is http://emofree.com/,
or try eft on Google. I tap lightly on a series of points on my body, mostly on the head, while repeating words that represent a problem, such as "my boss is mean to me", or "waking up for work," whatever has an emotional pain or problem that I can sense. I'm going to see David Smith again, to see if he can help with the Crohn's Disease.
