I went to a NLP/CBT/Hypnosis guy last year when i first split with the misses.
It only took 4 sessions with him and I had never felt so much confidence. It gives you a real buzz. I would recommend it to everyone.
I also have a mate who went to the same guy and before i did and he can't stop raving about it.
The only downside is that it's quite expensive for the sessions.

Unfortunately I then got back with the misses and 5 months later, she had managed to destroy all confidence and have made me waste my money! Doh!
I am thinking of going back though for a booster session.
