I long ago had a psychologist who used the technique in his practice and wanted to try it on me because he thought it might be helpful. So I decided, "Why not?" After two attempts, I just told him I didn't want to do it anymore. Frankly, the first time I pretended I was and the second time I just came out and told him I wasn't "under." Neither time I was no more hypnotized than I am right now sitting here writing this post.
