Its good,but like all other types of treatment,falls in2 branches.I did 12 sessions of freudian based hypnosis last march and wouldnt totally discount it.The one thing Id have my reservations about was the hypnotists attitude that id regain reality in a clap of thunder once i had isolated the trauma i was hiding from.He meant well but didnt understand the nature of dp.i also found it hard to trance because of the hypervigilance of my conscious mind,analysing each and every specific word,its meaning and the actual 'moment' of trance.Try hypnotic cds first and c how you work with them.If you can enduce a trancelike state,maybee go to a similar freudean based hypnotist and go with the flow.Although I'd suspect that you may get the best results from cds.Thats what i did anyway.
