never tried it for alcoholism, but i did try hypnosis therapy. it worked pretty fine for me. but not all people find it useful- it's not close to what you see at the movies. there is a scale from 1 to 12 (or 14 ...) on your reaction to hypnosis and most of us are on the 6-7. which is good enough. anyway, according to this:
http://www.ncbi.nlm.nih.gov/pubmed/15376606?ordinalp... combined with other treatments- hypnosis is a good treatment for Alcoholism.
good luck!!
